Answer 2

Answer: 33

Explanation:

P(x) = 2x 4 - x 2 + 3x - 1

To find the value of p(2) we simply substitute x = 2.

That is; wherever you see x, simply put 2

P(2) = 2
`(2)^(4)` -
`(2)^(2)` + 3(2) - 1

=2(16) - 4 + 6 - 1

= 32 - 4 + 6 -1

=28 + 6 -1

=34 - 1

=33

Therefore the value of P(2) is 33
