To determine

**Tofind:**The solution of the interval on x-axis in which curve lies under x-axis.

Expert Solution

The solution is interval on x-axis in which the curve lies under x-axis

**Given**:

**Concept used:**

The lowest value or the roots is taken as minimum point where the solution exist.

The highest value or the roots is taken as maximum point where the solution exist.

The graph can predict the solution below x-axis.

**Calculation:**

Required:

Solve the graphically the inequality

The solution is interval on x-axis in which the curve lies under x-axis.

Graph of

Hence, the solution is interval on x-axis in which the curve lies under x-axis
