Question

If p= -2 find the value of - 3p2+4p+7​

Answer 1

Answer:

The value of $3p^2+4p+7$ is 11.

Step-by-step explanation:

$f(-2)$ means putting the value of p=-2 in the equation.

Given

    $f(p)=3p^2+4p+7\\ \\ f(-2)=3(-2)^2+4 \cdot(-2) +7\\ \\ f(-2)=3 \cdot 4+(-8)+7\\ \\ f(-2)=12-8+7\\ \\ f(-2)=4+7=11$
