Question

The function f(x) = x^2 has been translated 9 units up and 4 units to the right to form the function g(x). Which represents g(x)?

g(x) = (x + 9)^2 + 4

g(x) = (x + 9)^2 − 4

g(x) = (x − 4)^2 + 9

g(x) = (x + 4)^2 + 9

Answer 1

Hello,

This is one way:

The vertex is (4,9)

1)g(4)=(4+9)²+4=13²+4≠9

2)g(4)=(4+9)²-4=13²-4≠9

3)g(4)=(4-4)²+9=0²+9=9 yes!!!!

4)g(4)=(4+4)²+9=8²+9≠9

Answer C
