1 and 2 are correct.

3.
[tex]f(g(x))=9(-x+3)-2=-9x+27-2=-9x+25[/tex]

4.
[tex]f(-2)=\dfrac{24}{3\cdot(-2)-2}\\ f(-2)=\dfrac{24}{-6-2}\\ f(-2)=\dfrac{24}{-8}\\ f(-2)=-3[/tex]

5.
[tex]f(x)=2x+2\\ y=2x+2\\ 2x=y-2\\ x=\dfrac{1}{2}y-1\\ f^{-1}(x)=\dfrac{1}{2}x-1\\\\ f^{-1}(4)=\dfrac{1}{2}\cdot4-1\\ f^{-1}(4)=2-1\\ f^{-1}(4)=1[/tex]
