Question

F(x) = -3x-3 g(x) =2x^3+2
Find f(6) and g(-3)

Answer 1

`f(6)=-21\\\\g(-3)=-52`

Explanation:

When given the following two functions,

`f(x) =-3x-3\\g(x)=2x^3+2`

One is asked to evaluate the functions for, (f(6)) and (g(-3)). One can do this by substituting the values (6) into the function (f) and (-3) into the function (g). These values will replace the parameter (x).

`f(6)=-3(6)-3\\`

Simplify,

`f(6)=-18-3\\f(6)=-21`

Now repeat this process for the guncion (g(x)) to evaluate for (g(-3))

`g(-3)=2(-3)^3+2`

Simplify,

`g(-3)=2(-27)+2\\g(-3)=-54+2\\g(-3)=-52`
