Question 2 of 10
2 points
if you vertically stretch the quadratic parent function, fx) = x2, by multiplying
by 7, what is the equation of the new function?
o a. g(x) = x2 - 7"
o b. g(x) = (x + 7)2
o c. g(x) = (7x)2
o d. g(x) = 7x2
submit

D. G(x) = 7x2

Step-by-step explanation:

Given a function f(x), the function kf(x) is stretched by a factor of k. In this case, if we stretch the function f(x) = x^2 by a factor of 7, the new function is going to be:

g(x) = 7x^2. Therefore, the correct option is option D.
