Answer: -11

Step-by-step explanation:

For this problem, it is important to look at the domains next to the function. In this problem there is a function for when x < 1 and when x ≥ 1. 3 is greater than 1, so we will use the second equation.

From there, plug in 3 for x and solve.

-2x - 5

-2(3) - 5
