Step-by-step explanation:
The first piece wise function is from interval (-3,-1). The line during this interval isnt constant so this means that f(x) must be a linear equation along interval -3 to -1. The line has a slope of 1. And if we keep continuing, our y intercept will be 3. So we can say that
[tex]f(x) = x + 3 \ : if \: - 3 \leqslant x < - 1[/tex]
Foe the 2nd, the interval is between -1 and 1.
The line is constant so f(x) is going to be equal to one y value. The y value is passed through is 5 so we can say that
[tex]f(x) = 5 \: if \: - 1 \leqslant x \leqslant 1[/tex]
