Question

find the value of p(x) = 3x3-2x2+5x-1 at x=2​

Answer 1

Step-by-step explanation:

$x = 2$

$p(x) = 3 {x}^{3} - 2 {x}^{2} + 5x - 1$

$p(2) = 3 {(2)}^{3} - 2 {(2)}^{2} + 5(2) - 1$

$24 - 8 + 10 - 1 = 25$

Therefore, it is your answer.

I hope it helps you. If you have any doubts, then don't hesitate to ask.

Answer 2

p(-2)=3(2)3-2(2)2+5(2)-1

=18-8+10-1

=10+10-1

=19
