$\"\"$

One of the curve has two zeros at $\"\"$ and $\"\"$ .

Since curve has two $\"\"$ -intercepts it is a second degree polynomial.

An other curve has zeros at $\"\"$ .

Since curve has one $\"\"$ -intercept it is a first degree polynomial.

Remaining curve has no $\"\"$ -intercept it is a constant function.

The second degree polynomial be the original function $\"\"$ .

The derivative of a second function is a first degree function that means $\"\"$ is a linear function.

The derivative of a first degree function is a constant function that is $\"\"$ .

Therefore second degree polynomial is correspond to $\"\"$ .

Simillarly first degree is correspond to $\"\"$ .

Constant function is correspond to $\"\"$ .
