Question

lf p(x) = 3x power3 - 4x- 5 find p(-1),p(-2)​

Answer 1

Answer:

p(-1)=3(-1)-4(-1)-5

=-3+4-5

=1-5

=-4

p(-2)=3(-2)-4(-2)-5

=-6+8-5

=2-5

=-3

Answer 2

p(x) = 3x³-4x-5

Step-by-step explanation:

p(-1)=

$3 \times { - 1}^{3 } - 4 x - 5$

= -3+4-5 = -4

p(-2)=

$3 \times ({ - 2}^{3}) - 4 \times ( - 2) - 5|$

= 3x(-8) + 8 -5 = -24 +3 = -21
