Question

Evaluate the piecewise function at the given values of the independent variable

Answer 1

A) For f(-1) we use the part of the piecewise function for when x < 0 because -1 < 0. Plug in -1 for x:

2(-1) + 3 = 1

b) For f(0), we use the part for when x $\geq$ 0.

4(0) + 5 = 5

c) For f(2) we use the part for when x $\geq$ 0.

4(2) + 5 = 13
