5. g(x) = (x + 4)2 - 2 g(x) = (x – 4)2 - 2 g(x) = (x – 2)2 + 4
What is the function for g(x) which is the transformation for ƒ(x) = x2 shown at the right?
g(x) = (x + 4)2 - 2
g(x) = (x – 4)2 - 2
g(x) = (x – 2)2 + 4
g(x) = x2 - 2

independent variable ↔ y axis
dependent variable ↔ output

7. g(x) = (x - 5)4 - 3 g(x) = (x + 3)4 - 5 g(x) = (x – 3)4 + 5
The graph of ƒ(x) = x4 is translated 5 down and 3 unit to the left to create the graph of g(x). Which is the equation of g(x)?
g(x) = (x - 5)4 - 3
g(x) = (x + 3)4 - 5
g(x) = (x – 3)4 + 5
g(x) = (x - 3)4 - 5
