Question

How do you evaluate the following polynomials for a domain value?P(x) = x² + 7x -3 find P(3)

Answer 1

the polynomial is:

`P(x)=x^2+7x-3`

so to ecaluate the function we have to replace x for the value, sor example for p(3) we replace x=3 so.

`\begin{gathered} P(3)=3^2+7\cdot3-3 \\ P(3)=9+21-3 \\ P(3)=27 \end{gathered}`
