In this lesson, we will learn how to find the domain and range of a piecewise-defined function.
Students will be able to
Q1:
Find the range of the function 𝑓(𝑥)=𝑥+5,𝑥∈[−5,−1],−𝑥+3,𝑥∈(−1,3].
Q2:
Determine the domain of the function 𝑓(𝑥)=𝑥,𝑥∈[0,1),1,𝑥∈[1,8],9−𝑥,𝑥∈(8,9].
Q3:
Determine the domain and the range of the function 𝑓(𝑥)=6,𝑥<0,−4,𝑥>0.
