Need help in solving these
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)
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.
