Question

Write the domain and range of the function in set-builder notation OR interval notation

Answer 1

Domain = (-inf, inf)

Range = [-1, inf)

Explanation:

Domain is the x axis they are continuing so its infinity on both sides

Range is the y axis. The lowest number is -1 and it appears like there is a dot there so we include it and notate using [. Upwards it continues to inf so we use ).
