1. So, f(x) = 4x-1

What happens if...

f(x+2)
f(x)+2
f(3x)
3f(x)

Thanks!

f(?) = 4?-1
f(0_0) = 4(0_0) -1
f(8----D) = 4(8-----D) -1
f(Hi) = 4(Hi)-1

You're not even funny

I'm not even trying to be, with the examples I've provided you should be able to solve your problems.
5. f(x+2) - The graph moves on the x-axis to the left two places
f(x)+2 - The graph moves up on the y-axis two places
f(3x) - The graph x-axis is stretched by 1/3
3f(x) - The graph y-axis is stretched by 3

if i remember correctly (:

Oh, is this question related to graph transformations?

To be honest with you I wasn't 100% sure what I was asking but I've got it now XD
