The function h is defined by h(x)=x^2-4x. Find h(4x). h(4x)= _____?

OpenStudy (anonymous):

Can somone please put this in a formula so I can solve it? I don't know how :/

OpenStudy (zale101):

Instead of h(x) you'll have h(4x), so the input x is replaced by 4x. Got it?

OpenStudy (anonymous):

Do I replace all x's with 4?

OpenStudy (zale101):

Replace all x's with just 4x, not 4 only.

OpenStudy (anonymous):

oh okay so is the answer h=x-11?

OpenStudy (anonymous):

@Zale101

Am I correct?
