Which of the following accurately shows the range of the function defined below?

Given:

A piecewise function

To find:

The range of the function.

Solution:

Range is the set of output values.

For , the function is       ...(i)

For , the function is .

Squaring each side.

Adding 2 on each side.

              ...(ii)

For , the function is .

Divide both sides by 2.

Adding 5 on each side.

                ...(iii)

From (i), (ii) and (iii), it is clear that the values of f(x) lies in the interval [2,∞).

So, the range of the given function is [2,∞).

Therefore, the correct option is b.

the correct answer is d
