Question

Find the value of f(–2) for the function f(x) = 4x + 10.A.–3B.–2C.2D.18

Answer 1

Given function is,

`f\mleft(x\mright)=4x+10.`

To find f(-2), put x=-2 in the above equation

`\begin{gathered} f\mleft(-2\mright)=4\mleft(-2\mright)\: +\: 10 \\ f\mleft(-2\mright)=-8+10 \\ f\mleft(-2\mright)=2 \end{gathered}`

The answer is option C) 2.
