Question

If p(x) =2x power 3 -3 x+5 find the value of p(1) and p(-2)

Answer 1

Answer:

p(1) = 4, p(-2) = -5

Step-by-step explanation:

p(X) = 2x3 - 3x + 5

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

       = 2 - 3 + 5

        = -1+ 5

         = 4

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

         =2(-8) + 6 + 5

        = -16 + 11 = -5
