Answer:
<h3>y = -32</h3>
Step-by-step explanation:
Substitute ; x =20 in given equation
By applying the wanted transformations, we will get the functions:
3) g(x) = 3x
4) g(x) = 5x

How to write vertical stretch and compression?</h3>
For a given f(x), we define a vertical stretch of scale factor k as:
g(x) = k*f(x)
While a vertical compression of scale factor k is written as:
g(x) = f(x)/k.
Here our function is y = f(x) = x
3) First, we want to apply a vertical stretch of scale factor of 3, so we will get:
g(x) = 3*f(x) = 3*x
4) Now we want to apply a vertical compression of scale factor of 1/5, then the function will be:
g(x) = 5*f(x) = 5x
