Question

evaluate the following value :

If p(x) = 4x5 - 3x4 -5x³+x²-8, then find p(-1).​

Answer 1

Answer:

Substitute -1 in the place of x

p(-1) = -4 -3 +5 +1 -8 = -9

p(-1) = -9

Answer 2

Answer:

p(-1)=30

Step-by-step explanation:

$p(x) = 4x^5-3x4 -5x^3+x^2-8$

Putting x=-1

$p(-1) = 4(-1)^5-3(-1)4 -5(-1)^3+(-1)^2-8\\ \\ p(-1) =-4+36+5+1-8\\ \\ p(-1)=32-2=30$
