**Given information** :

**Formula used** :

The equation of the straight line parallel to X-axis can be written as

The equation of the straight line can be written as

**Calculation** :

The graph right side of the

It is clear that all the Y coordinates of the points lie on that line is

The graph left side of the

It is clear that all the Y coordinates of the points lie on that line is

The graph between

It cut the Y-axis at

Therefore, the formula of the curve is

If we combine three equation and take
