Question

Find the domain of the following piecewise function

Answer 1

Domain is the numbers you can use

see, we have -1≤x<0 and 0≤x<5

so if it is in the range of -1 to 5, then it is in the function

it includes -1 but not 5 because we gots -1≤x but x<5

remember, in interval notation, [] is includes and () is not include
or
[] is ≤≥ and () is <>

so
[-1,5)
