Question

Evaluate the function f(p) = p2 + 3p + 1 for p = -2

Answer 1

p2 + 3p + 1
(-2)2 + 3(-2) +1
-4 +(-6) +1
-9

Answer 2

Answer: -1

Explanation:

The given function :
`f(p) = p^2 + 3p + 1`

To find : The value of the given function (
`f(p) = p^2 + 3p + 1`) at p =-2.

We substitute the value of p=-2 in the given function, we get

`f(-2) = (-2)^2 + 3(-2) + 1\\\\\Rightarrow\ f(-2)=4-6+1\\\\\Rightarrow\ f(-2)=-2+1\\\\\Rightarrow\ f(-2)=-1`

Therefore , the value of the given function at p=-2 = -1
