Question

The functions f and g are defined as followsf(x)=3x^3-2 g(x)=-3x+4find f(-3) and g(4)simplify answers as much as possibleF(-3)=g(4)=

Answer 1

Given the functions:

`\begin{gathered} f(x)=3x^3-2 \\ \\ g(x)=-3x+4 \end{gathered}`

It's required to find f(-3) and g(4). Substituting x = -3 in the first function:

`\begin{gathered} f(-3)=3(-3)^3-2 \\ f(-3)=3(-27)-2 \\ f(-3)=-81-2 \\ f(-3)=-83 \end{gathered}`

Substituting x = 4 in the second function:

`\begin{gathered} g(4)=-3(4)+4 \\ \\ g(4)=-12+4 \\ \\ g(4)=-8 \end{gathered}`

f(-3) = -83

g(4) = -8
