Question

The functions f and g are defined as follows.= f (x) = 3x (power of 3) + 5 g(x) = 2x - 1Find f(−4) and g(−6). Simplify your answers as much as possible. f(−4)=g(−6)=

Answer 1

`\begin{gathered} f(x)=3x^3+5 \\ g(x)=2x-1 \end{gathered}`

Evaluating for every function:

`\begin{gathered} f(-4)=3(-4)^3+5=3(-64)+5=-192+5=-187 \\ answer: \\ f(-4)=-187 \end{gathered}`
`\begin{gathered} g(-6)=2(-6)-1=-12-1=-13 \\ answer: \\ f(-6)=-13 \end{gathered}`
