Question

Given h(x) = 5x – 3 and m(x) = -2x^2 what is (h o m)(5)=

Answer 1

`(h\circ m)(5)=-253`

Step-by-step explanation:

Given that:

h(x) = 5x - 3

m(x) = -2x^2,

To find

`(h\circ m)(5)`

We first of all need to find

`(h\circ m)(x)`
`\begin{gathered} (h\circ m)(x)=5(-2x^2)-3 \\ =-10x^2-3 \end{gathered}`

Substituting x = 5 in the last equation, we have:

`\begin{gathered} (h\circ m)(5)=-10(5^2)-3 \\ =-10(25)-3 \\ =-250-3 \\ =-253 \end{gathered}`
