Answer:
Option B. It represents a nonlinear function because its points are not on a straight line.
Step-by-step explanation:
Let

we know that
If point A,B and C are on a straight line
then
The slope of AB must be equal to the slope of AC
The formula to calculate the slope between two points is equal to

<em>Find the slope AB</em>

substitute in the formula

<em>Find the slope AC</em>

substitute in the formula

so

Points A, B and C are not on a straight line
therefore
It represents a nonlinear function because its points are not on a straight line
Stretched vertically three times because you take the result of x^2+4x+4 aka (x+2)^2 and then multiply it by 3 for 3 times the output
