Hey I am left with this question and I have no clue how to do it(adsbygoogle = window.adsbygoogle || []).push({});

y = -3 f(x+2) - 7 (Function help!)

1. f(x) = x

2. f(x) = x^2

3. f(x) = |x|

4. f(x) = 1/x

5. f(x) = (square root of 2) how do i write that out?

Basically I am suppose to substitute the 5 things into the equation and the graph it. I am confident that I can graph it with no problems. However, I cant do the first part, which is to put the 5 f(x) things into the equation

Help plz, its due tomorrow:(

I'll check for replies frequently so if u can help me..GREAT!

Thx in advance guys
