Question

I need to know the answers to these 4 problems

Answer 1

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

10)

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

11)

$f(x)-g(x)=3x+2-2x^2=-2x^2+3x+2=(x-2)(x+\frac{1}{2})$

12)

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

13)

$h(g(x))=\frac{-4}{2x^2+3}$
