Question

Find the values of P(1), P(-1), P(0), P(-2), where P(x) = 3xcube
4xsquare+ 5x + 7.
​

Answer 1

Step-by-step explanation:

p(x)=3x³+4x²+5x+7

p(1)=3(1)³+4(1)²+5(1)+7

=3+4+5+7=19

p(-1)=3(-1)³+4(-1)²+5(-1)+7

=3(-1)+4(1)-5+7

= -3+4+2=3

p(0)=3(0)³+4(0)²+5(0)+7=7

p(-2)=3(-2)³+4(-2)²+5(-2)+7

=3(-8)+4(4)-10+7

= -24+16-3

=-27+16

= -11
