F(x)=9x+5, find f^-1(x).

interchange the role of x and y

x=9y+5

x-5=9y

x-5 =y

9

so,f^-1(x)= x-5

9

hope it helps.

i belive those are the ones that are under 90 degreese.

so far i think you have the right thing going for you just remember soh cah toh

step-by-step explanation:

sine over hypotenuse
