In General for f(ax) if a >1 f(x) is compressed horizontaly
a< 1 f(x) is stretched horizontaly
See attachment for examples
So I came across this question:
y = f(9x), what does this do to the function y=f(x).
It multiplies the x value by 9 correct? Therefore, stretching the horizontal axis by 9? I put that and it said it was incorrect.
Is that even right? Or is there other stuff that happens?
