G={(3,0), (4,6), (5,-5), (6,5)} h(x)=3x-8

Find the following.
g^-1(-1)=
h^-1(x) =
(h o h^-1)(4) =

Look, when you want to do something like put it like x^2. x2 could mean x² or x₂. so to clear confusion, know the notation. to find the product multiply the x's and you get -8x and the y's and you get 6y. since it's all being multiplied it is just -8x6y, or answer a. although the better answer is -48xy(combining -8 and 6) because you should multiply constants whenever you can.
