The entire graph of the function h is shown in the figure below. Write the domain and range of h as intervals or unions of intervals.

Solution

Domain - value of x can be starting from -5(represented by dot) to 1(1is not included) then from 2 to 3 in which both 2 and 3 are not included as they are represented by circle.

Domain : [-5,1) U (2,3)

Range: (-3,-1] U (-1,4)
