Question

If f(x) = -7x – 10, what is f(6)? If it does not exist, enter DNE.

Answer 1

`f(x)=-7x-10`

To determine f(6), simply replace the x-variable in the function above with 6.

`f(6)=-7(6)-10`

Then, simplify.

`\begin{gathered} f(6)=-42-10 \\ f(6)=-52 \end{gathered}`

Therefore, f(6) is -52.
