Question

Use the following function rule to find (2). f(x) = (-5 - 2x)? ? f(2) =

Answer 1

Using the function f(x) = -5 - 2x, in order to evalute the value of f(2), we just need to use the value of x = 2 and calculate the value of the function. So we have that:

$\begin{gathered} f(x)=-5-2x \\ f(2)=-5-2\cdot2 \\ f(2)=-5-4 \\ f(2)=-9 \end{gathered}$

So the value of f(2) is -9.
