Question
Consider this absolute value function.𝑓(𝑥)=|𝑥+3|If function f is written as a piecewise function, which piece will it include? A. 𝑥+3,𝑥≥-3 B. 𝑥+3,𝑥≥3 C. -𝑥+3,𝑥<-3 D. -𝑥−3,𝑥<3
Solution
The absolute value function 𝑓(𝑥)=|𝑥+3| can be written as a piecewise function as follows:
f(x) =
- (𝑥+3) when 𝑥 ≥ -3
- -(𝑥+3) when 𝑥 < -3
So, the function will include pieces A. 𝑥+3,𝑥≥-3 and C. -𝑥-3,𝑥<-3.
