A teacher was explaining the concept of polynomials and types of polynomial based on their degree. The polynomial degree is the highest variable power in a polynomial. A polynomial of degree \(1\) is said to be a linear polynomial. A polynomial of degree \(2\) is a quadratic polynomial. A polynomial of degree \(3\) is a cubic polynomial. The teacher also explain the concept of graphical representation of the polynomial to the students.
 
Based on this situation answer the following question.
 
1. Which of the following polynomial is graphically represented by a parabola?
 
2. The zeros of the polynomial are points where the graph 
 
3. If \(\frac{1}{2}\) and \(\frac{-2}{3}\) are zeros of the polynomial then find the polynomial expression.
 
4. Number of zeros of the polynomial represented by the below graph
