Answer:
[tex](h\circ m)(5)=-253[/tex]Explanation:
Given that:
h(x) = 5x - 3
m(x) = -2x^2,
To find
[tex](h\circ m)(5)[/tex]We first of all need to find
[tex](h\circ m)(x)[/tex][tex]\begin{gathered} (h\circ m)(x)=5(-2x^2)-3 \\ =-10x^2-3 \end{gathered}[/tex]Substituting x = 5 in the last equation, we have:
[tex]\begin{gathered} (h\circ m)(5)=-10(5^2)-3 \\ =-10(25)-3 \\ =-250-3 \\ =-253 \end{gathered}[/tex]
