Question

What is the answer to this

Answer 1

Hello from MrBillDoesMath!

Answer:

f(-1) =   2

f(1) =    6

f(2) =   11

Discussion:

Let f(x) = 2x^3 - 3x^2 + 7. Then

f(-1) =   2 (-1)^3 - 3 (-1)^2 + 7 = -2 -3 + 7 = -5 + 7 =  2

f(1) =    2(1)^3 - 3(1)^2 + 7 = 2 -3 + 7 = -1 +7 = 6

f(2) =   2(2)^3 - 3(2)^2 + 7 =  2*8 - 3*4 + 7 = 16-12+7 = 11

Thank you,

MrB
