Question

Consider the polynomial function P(x)=2x⁴ +3x²+12.Find P(−2).

Answer 1

The value will be 56

Explanation:

We have given polynomial
`P(x)=2X^4+3X^2+12`

We have to find P(-2)

For finding P(-2) we have to put x = -2 in the polynomial

So P(-2) =
`2* (-2)^(4)+3* (-2)^2+12=32+12+12=56`

So value of P(-2) will be 56

For finding any value we have to just put that value in the polynomial
