Question

I need to know the answers to these 4 problems

Answer 1

`\begin{gathered} f(x)=3x+2 \\ g(x)=2x^2 \\ h(x)=(-4)/(x+3) \end{gathered}`

10)

`f(x)\cdot g(x)=(3x+2)\cdot(2x^2)=6x^3+4x^2`

11)

`f(x)-g(x)=3x+2-2x^2=-2x^2+3x+2=(x-2)(x+(1)/(2))`

12)

`g(f(x))=2(3x+2)^2=2(9x^2+12x+4)=18x^2+24x+8`

13)

`h(g(x))=(-4)/(2x^2+3)`
