Question

Evaluate p(x)= -3 + 4x when x= -2,0, and 5.

Answer 1

To evaluate the function we need to use the provided values as inputs.

For x = -2, we have:

$\begin{gathered} p(-2)=-3+4\cdot(-2) \\ p(-2)=-3-6=-9 \end{gathered}$

For x = 0, we have:

$\begin{gathered} p(0)=-3+4\cdot0 \\ p(0)=-3 \end{gathered}$

For x = 5, we have:

$\begin{gathered} p(5)\text{ = -3+4}\cdot5 \\ p(5)\text{ = -3+20=17} \end{gathered}$
