Chapter 2 - 2.2 - Functions - 2.2 Exercises - Page 182: 30


a) -1; b) 2; c) 6

Work Step by Step

We are given the function: $f(x)=\begin{cases} 2x+1,x\lt 0\\ 2x+2,x\geq 0 \end{cases}$ a) Compute $f(-1)$: As $-1\lt 0$, we have: $f(-1)=2(-1)+1=-1$ b) Compute $f(0)$: As $0\gt 0$, we have: $f(0)=2(0)+2=2$ c) Compute $f(2)$: As $2\gt 0$, we have: $f(2)=2(2)+2=6$
