Which function described below has the greatest rate of change? I WILL MARK BRAINLIEST​

Mathematics

Answer:

C III

Step-by-step explanation:

The rate of change of a linear function is the slope.

f(x) = mx + b is the equation of a linear function whose graph is a straight line. m is the slope.

I f(x) = 4x - 3;   m = slope = 4

II f(x) = 1/2 x + 5;   m = slope = 1/2

III We can use two points to find the slope.

Let's use points (1, 6) and (2, 12).

m = slope = (y2 - y1)/(x2  x1) = (12 - 6)/(2 - 1) = 6/1 = 6

The three slopes are 4, 1/2, 6.

The greatest rate of change is 6, so the answer is C III.

Answer:

Range = (7,5,-1,-9)

Point 1 = ( -3, 7)

Point 2 = ( -2, 5)

Point 3 = ( 1, -1)

Point 4 = ( 5, -9)

Step-by-step explanation:

g(x)= 1-2x

The domain is x.

The range is y.

g(x) is the function.

To solve this you just input each number from the domain into the function.

g(x) = 1 - 2(-3)

-2 × -3 = positive 6

It is a positive because a negative multipled by a negative equals a positive. This means it is not 1-6 because it is not a negative, it would be 1+6.

1 + 6 = 7

g(x) = 1 -2(-2)

-2 × -2 = positive 4

1 + 4 = 5

g(x)= 1 - 2(1)

-2 × 1 = -2

Since it is multipled 1 time it will be -2. So the equation is still 1-2.

1 - 2 = -1

g(x)= 1 - 2(5)

-2 × 5= -10

A negative multipled by a positive is a negative.

1 - 10 = -9

Now that you have all the numbers put them in parentheses things like the domain

Range = {7,5,-1,-9}

To graph it you need to put in each point by finding the first number of the domain and range and that is your point.

The first point would be (-3,7) and so on and so forth.

Which expression is the factored form of 2/3x+4 ?
frosja888 [35]

Answer:

Option C.

Step-by-step explanation:

The given expression is

\dfrac{2}{3}x+4

We need to find the factored form of the given expression.

The given expression can be rewritten as

\dfrac{2}{3}x+(\dfrac{2}{3}\times \dfrac{3}{2})\times 4

\dfrac{2}{3}x+\dfrac{2}{3}(6)

It is clear that \frac{2}{3} is common.

Taking out common factors, we get

\dfrac{2}{3}(x+6)

It is the factored form of the given expression.

Hence, the correct option is C.

What is the domain of the function y=tan (x/8)<br> Please Help<br> 15 Points
7nadin3 [17]

1. You have the function y=tan(\frac{x}{8} )

2. You know that y=\frac{sinx}{cosx} with cosx\neq 0, because the division by zero is not defined. So , cosx=0 for \frac{(2n+1)\pi}{2} where n is a integer number.

3. Then, to find the domain of the function given in the problem, you must make \frac{x}{8} \neq \frac{k\pi}{2}  \\ x\neq 4k\pi

Where k is odd number.

4. Therefore:

x\neq 4\pi (2n+1)

5. Finally, the domain is: 4\pi (2n+1)

The answer is: 4\pi (2n+1)
