Question

Dose anyone know the answer??

Answer 1

In any function y = f(x) , set of all possible values of x define the domain of f(x), in the graph The curve in terms of x-axis(in 1st & 3rd quadrant) goes from -4 to -2(doesnt include -2).

So domain = [-4, -2)

Similarly, in 2nd and 4th quadrant, for x-axis

It goes from 2 to 5 (doesnt include 2 & 5)

So domain = (2, 5)

Hence,

Domain of the f(x) is [-4, -2) U (2, 5).

Range tells the possible values of y, for this function it goes from -5 to +3(doesnt include 3).

Range is [-5, 3)
