Answer 3

f(x-2)=4((x-2)+1)^2-3=4(x-1)^2-3.
So basicly you just replace the x with the value between brackets.

Answer 4

Okay, I was understanding that but, I couldn't figure out what the equation would be

Answer 5

Which equation are talking about ?

Answer 6

f(2x)

Answer 7

That would be f(2x)=4(2x+1)^2-3

Answer 8

Okay, I see how it works. Thank you!

Answer 9

you're welcome !

Answer 10

f(x-2)=4((x-2)+1)^2-3=4(x-1)^2-3

Answer 11

In that equation, why is there two "=4's"
