I need to know how to solve this problem, you don't necessarily have to answer it, i just don't know the name and the steps to solving it because I missed out on a class that explained it, so I'm in the dark

f(-3) = -16

Step-by-step explanation:

Given piecewise function is,

f(x) = 5x - 1       If x < -2

        x + 3       If x ≥ -2

We have to find the value of he function when x = -3

Since x = -3 is less than x = -2,

Piece of the function to be considered,

f(x) = 5x - 1

f(-3) = 5(-3) - 1

f(-3) = -16
