So I’ll do question 3. So normally you see f(x)= something plus x (something like that) you see it as a function of x.
So that notation of f(-1) means the function of -1. Which means you need to sub in -1 for x.
f(x)=-5x+5
f(-1)=-5(-1)+5
Negative times a negative is a positive
f(-1)=5+5
f(-1)=10
O definitely does. I think Z and W do as well.
Y, K and P don't because they can't be rotated and map onto themselves.

Step-by-step explanation:
Solve for g by simplifying both sides of the inequality, then isolating the variable.
