**Step 1: **

The equation is

.

To identify whether the equation

, which defines the quadratic expression is a function.

The equation

tells us to take an input

.

For any kind of value that

, we acquire only one value for

.

**Step 2:**

Consider

.

Substitute

in

.

Consider

.

Substitute

in

.

For two various values that

, we gain two different values because that

.

Hence, the equation specifies

as a role of

.
