Question

The functions fand g are defined as follows.f(x)=-4x-1g(x) = -2x³-3Find f(7) and g (-2).Simplify your answers as much as possible.f(¹) = []8 (-2) = 000XS

Answer 1

Step 1

Given;

`\begin{gathered} f(x)=-4x-1 \\ g(x)=-2x^3-3 \end{gathered}`

Step 2

Find f(7)

`f(7)=-4(7)-1=-29`

Find g(-2)

`g(-2)=-2(-2)^3-3=13`

Answers;

`\begin{gathered} f(7)=-29 \\ g(-2)=13 \end{gathered}`
