Question

Just making sure 1 and 2 are corrcet

Answer 1

1 and 2 are correct.

3.

`f(g(x))=9(-x+3)-2=-9x+27-2=-9x+25`

4.

`f(-2)=(24)/(3\cdot(-2)-2)\\ f(-2)=(24)/(-6-2)\\ f(-2)=(24)/(-8)\\ f(-2)=-3`

5.

`f(x)=2x+2\\ y=2x+2\\ 2x=y-2\\ x=(1)/(2)y-1\\ f^(-1)(x)=(1)/(2)x-1\\\\ f^(-1)(4)=(1)/(2)\cdot4-1\\ f^(-1)(4)=2-1\\ f^(-1)(4)=1`
