Question

What is the effect on the graph of the function f(x) = x2 when f(x) is changed to f(x) − 4?

Answer 1

F(x) -4 shifts it down 4 units from f(x)

Explanation:

When we add or subtract from f(x) this causes a shift in the vertical direction.

When we add it shifts it up.

When we subtract is shifts it down

F(x) -4 shifts it down 4 units
