Question

what is the effect on the graph of the function f(x) = x² when f(x) is changed to f(x) + 9A) shifted up B) shifted left C) shifted rightD) shifted down

Answer 1

When we add a constant on a f(x) graph we have

• f(x) + a ⇒ graph shifted up

,

• f(x) - a ⇒ graph shifted down

Therefore, let's see if it's shifting up or down, we have

`f(x)+9`

9 is positive, then it's shifting up 9 units.
