Question 8 • LUSD-Int Math 2(A) LT2 Rational and Irrational Numbers (A-G)

The vertex form of a function is g(x) = (x – 3)2 + 9. How does the graph of g(x) compare to the graph of the function f(x) = x2?

Answer
A
g(x) is shifted 3 units left and 9 units up.
B
g(x) is shifted 3 units right and 9 units up.
C
g(x) is shifted 9 units left and 3 units down.
D
g(x) is shifted 9 units right and 3 units down.

Explanation

The vertex form is g(x) = (x − h)² + k, which shifts the graph of x² right by h units and up by k units. Here, h = 3 and k = 9, so g(x) is shifted 3 units right and 9 units up. This matches choice B.
