Which of the following are the most likely factors of the function graphed above?

Mathematics
1 answer:
alexandr402 [8]3 years ago
3 0

Answer: OPTION C.

Step-by-step explanation:

You can observe in the graph that the solutions of the Quadratic function are:

x=-5\ or\ x=1

By definition, the parabola intersects the x-axis when the value of "y" is zero, applying the Addition property of Equality:

x+5=-5+5\\\\x+5=0

Applying the Subtraction property of Equality:

x-1=1-1\\\\x-1=0

The Zero Product property states that:

If a*b = 0  then a = 0\ or \ b = 0

Then, you know that:

(x-1)(x+5)=0

Therefore the most likely factors of the function graphed above are:

(x-1)(x+5)

Which equation represents the function graphed on the coordinate plane? g(x) = |x – 4| – 10 g(x) = |x 4| – 10 g(x) = |x – 10| 4
AfilCa [17]

You can use the fact that when mode is used, negative and positive all values become non-negative.

The equation that represents the function graphed on the given coordinate plane is given by

Option B: g(x) = |x+4| -10 is the equation which represents the function graphed on the coordinate plane.

<h3>How to know what function is graphed on the coordinate plane?</h3>

We see what points it goes through, what type of nature it is showing where (like for example, the given function firstly goes down straightly, then rise up straightly after x = -4 ). We can see on what value of x, does the function become 0.

Many such graphical analysis help us to analyze which function can represent the given graph.

<h3>How to analyze given graph?</h3>

The graph contains straight lines, so it must be linear.

The graph contains a twist in the direction where it was going initially and changes the direction. This shows that the graph is using something else than just a regular linear equation.

The graph turns up after it goes through x = -4.

Let we try to make equation of straight lines before and after x = -4 which the graph follows.

The first line goes 1 block down (1 block is of 2 units) on y axis as we go 1 block left on x axis. Thus the slope will be -2/2 = -1 (we take slope as rise/run and since rise was down thus it is taken as -ve rise).

The slope intercept form of this line would be

y = mx + c\\&#10;y = -x + c

Since the line passes through point x = -4, y = -10, thus this point must satisfy the equation of that line since an equation represents the family of points which  make up the given line.

Thus,

y = -x + c\\&#10;-10 = -(-4) + c\\&#10;-10 = 4 + c\\&#10;c = -10 -4 \\&#10;c = -14

Thus, the equation of first line would be y = -x -14

The equation of second line, let be y = mx + c.

Since the second line intersects the y axis at y = -6, thus the y intercept of this line is -6 or c = -6.

Since the line rises 1 block( = 2 units) as one block of run happens on x axis in left direction (we take left as positive and right direction run as negative. This is standard sign convention used by most of the mathematical community. Conventions are just to remove ambiguity on international level). Thus, the slope of this line is 2/2 = 1

Thus, m = 1 or the equation of this line would be:

y = x - 6

We can rewrite both the lines as:

y = -x -14\\&#10;and \\&#10;y = x -6\\&#10;\\\\&#10;y = -x -10 -4\\&#10;and\\&#10;y = x - 10 + 4\\&#10;\\\\&#10;y = -10 - (x + 4)\\&#10;and\\&#10;y = -10 + (x + 4)

But the graph has first line till x <= -4 and second line from x >= -4

Thinking carefully on this fact, we can see that when x <= -4 in first line, the -(x+4) is positive or 0

Similarly, for second line, when x >= -4,

the (x+4) is positive or 0

Thus, we can merge both equations using mode:

y = -10 + |x+4|

which will make x+4 to stay positive all the way. Thus, when x <= -4, this will simulate the first line, and when x >= -4, this will simulate the second line.

Note that at x = -4, both the lines have y = -10.

Thus, Option B: g(x) = |x+4| -10 is the equation which represents the function graphed on the coordinate plane.

Help with 5b please . thank you.​
Allushta [10]

Answer:

See explanation

Step-by-step explanation:

We are given f(x)=ln(1+x)-x+(1/2)x^2.

We are first ask to differentiate this.

We will need chain rule for first term and power rule for all three terms.

f'(x)=(1+x)'/(1+x)-(1)+(1/2)×2x

f'(x)=(0+1)/(1+x)-(1)+x

f'(x)=1/(1+x)-(1)+x

We are then ask to prove if x is positive then f is positive.

I'm thinking they want us to use the derivative part in our answer.

Let's look at the critical numbers.

f' is undefined at x=-1 and it also makes f undefined.

Let's see if we can find when expression is 0.

1/(1+x)-(1)+x=0

Find common denominator:

1/(1+x)-(1+x)/(1+x)+x(1+x)/(1+x)=0

(1-1-x+x+x^2)/(1+x)=0

A fraction can only be zero when it's numerator is.

Simplify numerator equal 0:

x^2=0

This happens at x=0.

This means the expression,f, is increasing or decreasing after x=0. Let's found out what's happening there. f'(1)=1/(1+1)-(1)+1=1/2 which means after x=0, f is increasing since f'>0 after x=0.

So we should see increasing values of f when we up the value for x after 0.

Plugging in 0 gives: f(0)=ln(1+0)-0+(1/2)0^2=0.

So any value f, after this x=0, should be higher than 0 since f(0)=0 and f' told us f in increasing after x equals 0.

(NEED DONE QUICK) Two angles are supplementary. One of the angles measures 4(2x+9) and the other angle measures 2(4x-8) what is
Studentka2010 [4]

Answer:

x=10

Step-by-step explanation:

Supplementary angles are angles equal to 180°.

Therefore:

4(2x+9)+2(4x-8)=180

Now that we have our equation, let's distribute the 4 and the 2 into the parentheses they are next to:

8x+36+8x-16=180

Combine like terms:

16x+20=180

Subtract 20 from both sides of the equation:

16x=160

Divide by the coefficient of x, which is 16:

x=10

~

Check your work by substituting 10 into one of the equations above:

8(10)+36+8(10)-16=180

80+36+80-16=180

180=180

It's correct!
