Range of a Function

Range of a function- It is simply the set of possible outputs for a defined domain.

Range of a given function depends on the  domain of given function
Examples:

1)  y=4x²

Domain  x=ℝ

Range    y≥0

2)  y=3√x

Domain x≥0

Range    y≥0

3)  y=√x            2∠x≤3

Domain  x=(2,3)

Range     y=(√2,√3)
