Question

If you vertically compress the square root parent function by a factor of 1/3

what is the equation of the new function?
A. G(x)=-3square root of x
B. G(x) =- square root of 3x
C. GX) = 1/3 square root of x
D. G(X) = -1/3 square root of x

Answer 1

9514 1404 393

Answer:

C. G(x) = (1/3)√x

Explanation:

The vertical scale factor multiplies the function value. When the scale factor is 1/3 (called "compression by a factor of 1/3"), then the new function is ...

g(x) = 1/3·f(x)

g(x) = 1/3√x
