Question

What transformation to the linear parent function, f(x) = x, gives the function g(x) = x + 8?

A. Shift 8 units left.
B. Shift 8 units down.
C. Vertically stretch by a factor of 8.
D. Shift 8 units right.

Answer 1

Answer:D

Explanation:

Answer 2

Shift 8 units up

Explanation:

The given function is;

f(x)=x

and

g(x)=x+8

The function f(x) has its y-intercept at y=0.

The function g(x)=x+8 has its y-intercept at y=8

This implies that; the linear parent function f(x)=x is shifted up 8 units to obtain g(x)=x+8.
