Answer:

Step-by-step explanation:

Function transformations are easy to do when you remember four rules:

adding or subtracting in the function moves it left and right
adding or subtracting outside the function moves it up or down
multiplying and dividing to the function stretches or compresses it

Here the 2 is being multiplied to the function which vertically stretches the function.

The negative sign flips it over the x-axis.

Answer:

Option a is right.

Step-by-step explanation:

Parent funciton is

$f(x) = x^3$

The new graph is

$f(x) = -2x^3$

Since there is no change for x, there is no horizontal shift.

BUt since sign is changed there is a reflection on the line y=0 i.e. x axis.

Also new y is -2x^3 , -2 indicates the vertical shrink by scale factor 1/2

Option a is right

i.e. there is a reflection on x axis also there is a compression of scale factor 2 vertically.

Answer:

Part 1)

Part 2)

Step-by-step explanation:

We are given:

$f(x)=5x+1\text{ and } g(x)=x^2-9$

And that:

$h(x)=f(x)/g(x)$

And we want to now for which values of x is h(x) undefined.

So, by substitution:

$\displaystyle h(x)=\frac{5x+1}{x^2-9}$

Remember that for rational functions, the function will be undefined if and only if the denominator is 0.

This is because we cannot divide by 0.

So, to find the values for which the denominator is 0, set the denominator to 0 and solve for x. Therefore:

$x^2-9=0$

Add 9 to both sides:

$x^2=9$

Take the square root of both sides. Since we are taking an even-root, we will need plus/minus. Therefore:

$x=\pm 3$

So, h(x) is undefined for ±3.

Our answer is A.

We are given:

$f(x)=3^x\text{ and } g(x)=3^{2x}-3^x$

And we want to find:

$h(x)\text{ if } h(x)=f(x)-g(x)$

So:

$h(x)=3^x-(3^{2x}-3^x)$

Distribute:

$h(x)=3^x-3^{2x}+3^x$

Combine like terms:

$h(x)=2(3^x)-3^{2x}$

Rewrite:

$h(x)=2(3^x)-(3^x)(3^x)$

Factor out:

$h(x)=3^x(2-3^x)$

So, our answer is C.
