The function f is defined as follows. f(x)=4x^2 - 9 If the graph of is translated vertically upward by 4 units, it becomes the graph of a function g. Find the expression for g(x).

Question

The function is f(x)= 4x²-9

Answer 1

Hello Daniela,

If f(x)=4x²-9 and g is f vertically upward by 4 units (same x value, y value is 4 unit higher), then g(x)=4x²-9+4=4x²-5
