Question

If f(x)=2x +6 and g(x) =x³ , what is (g•f) (0)

Answer 1

Hi Melanie,

To solve this, you would multiply the two eqns by each other.

(g*f)(0) = g(x) * f(x)

= x³ (2x + 6)

= 2x⁴ + 6x

since you are looking for the value at 0, you would just solve the eqn at 0 by substitution 0 at all the x's.

Hope this helps!
