Describe the transformations made on this function:(stretch/compression, reflect, left/right, up/down)

The function we have is:

f(x)=\frac{1}{2}(x-7)^3+6

Since this is a cubic function, we start with the parent cubic function (the simplest form of the cubic function):

f(x)=x^3

And compare it to the given function.

The first thing we can note is that there was a subtraction of 7 to the value of x:

x\longrightarrow x-7

When we add a number to the x value, the graph moves to the left, and when we subtract a number to the x value, the graph moves to the right.

So the first transformation is moving to the right 7 units.

Next, we have that there was +6 added to the expression --> When you add a number to the function, the graph moves up, and when you subtract a number to the function, the graph moves down.

In this case, since we added a constant value of 6, the graph is translated 6 units up.

The second transformation is moving up 6 units.

Finally, let's analyze the effect that the 1/2 has on the function.

We can compress or stretch the graph of a function by multiplying the x by a constant (a number). If the number of between 0 and 1, there is a stretch, and if the number is greater than 1 there is compression.

In this case, the number next to the x is:

\frac{1}{2}=0.5

Since the number is between 0 and 1 there is a stretch of the function.

In summary:

Answer:

Translation of 7 units to the right

Translation of 6 units up

Stretch of the function of 0.5

kenny6666 [7]
First put in ascending order.
0, 2, 2, 4, 5, 6, 7
The median is the middle number: 4
The mode is the number that repeats the most often: 2
The mean is the average. Add the numbers and divide by 7.

What are the real and complex solutions of the polynomial equation? x^3-8=0. with imaginary numbers
seraphim [82]

Answer:

Solutions are 2,  -1 +  0.5 sqrt10 i  and -1 - 0.5 sqrt10 i

or 2,  -1 +  1.58 i  and -1 - 1.58i

(where the last 2 are equal to nearest hundredth).


Step-by-step explanation:

The real solution is x = 2:-

x^3 - 8 = 0

x^3 = 8

x = cube root of 8 = 2

Note that a cubic equation must have  a total of 3 roots ( real and complex in this case).  We can find the 2 complex roots by using the following identity:-

a^3 - b^3 = (a - b)(a^2 + ab + b^2).

Here  a = x and b = 2 so we have

(x - 2)(x^2 + 2x + 4) = 0

To find the complex roots we solve x^2 + 2x + 4 = 0:-

Using the quadratic formula x = [-2 +/- sqrt(2^2 - 4*1*4)] / 2

= -1 +/- (sqrt( -10)) / 2

= -1 +  0.5 sqrt10 i  and -1 - 0.5 sqrt10 i

Explain why 256 + 4 is equivalent to (200 + 4) + (40+4) + (164)​
laiz [17]

The expression 256 + 4 is equivalent to (200 + 4) + (40+4) + (16+4) according to distributive and commutative property of addition.

Given the expression 256 + 4. This can be solved using the partial sum expressed as:

256 + 4

256 + 4

= (200 + 40 + 16) + 4

According to the commutative property, A+B = B+A

The arrangement does not affect the result. Hence;

  • (200 + 40 + 16) + 4 = 4 +  (200 + 40 + 16)

Using the distributive law;

  • 4 +(200 + 40 + 16) = (200 + 4) + (40 + 4) + (16 + 4)

Hence the expression 256 + 4 is equivalent to (200 + 4) + (40+4) + (16+4) according to distributive and commutative property of addition.

A circular coaster has a diameter of 5 inches. What is its area? write your answer using π.
Verizon [17]

Answer:

Step-by-step explanation:

Diameter=5 inches

Area= πr^{2}

<u>r is the radius of coaster.</u>

<u>Radius=diameter/2</u>

Substitute the value of D:

r=5/2

Now

Area=π \frac{5}{2} ^{2}

Area=π(\frac{25}{2})

Area=12.5π sq.inches
