Problem #1

For f(x)=-6x3+10

find f(4) and f(-4)





Problem #2

For g(x)=20-5x2

find f(1) and f(-1)

  • math -

    Online "^" is used to indicate an exponent.

    f(x) = -6x^3 + 10

    F(4) = (-6 * 4 * 4 * 4) + 10

    f(-4) = (-6 * -4 * -4 * -4) + 10

    I'll let you do the calculations.

    In the second problem, there is no difference, since a negative times a negative is a positive.
