Find the indicated outputs for f(x)= 5x^2-5x.
F(0) = 0
f(-1)= 1
f(2)= 45

is this right?

  • Math -

    f(0) = 0 is right
    f(-1) = 10
    f(-1) = 5(-1)^2 - 5(-1)
    = 5(1) - (-5)
    = 5 + 5
    = 10
    f(2) = 10
    f(2) = 5(2)^2 - 5(2)
    = 5(4) - 10
    = 20 - 10
    = 10
    HOPE THIS HELPS!!
