Identify the value that is NOT in the range of the piecewise

Identify the value that is NOT in the range of the piecewise function. A) -2 B) 1 C) 2 D) 5

Solution

Domain means the values on x axis and

Range means the values on y axis.

As we can see from the graph that on y axis all the values from 0 to 4 is lying in the range of BLUE curve.

Maximum value is 4.

Therefore from the options only \'5\' is the value which does not lie in the range of function.

So option D is correct answer.
