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

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

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
