Find the number of real zeros of the polynomial $y = p(x)$ from the given figure.

Are the following statements 'True' or 'False'? Justify your answers.
If two of the zeroes of a cubic polynomial are zero,then it does not have linear and constant terms.

The number of polynomials having zeroes as $-2$ and $5$ is

The product of two polynomials is $x^{2}-x-72$ and if one of the polynomials is $(x+8)$,then the other polynomial is $\ldots \ldots \ldots \ldots . .$

The zero of the linear polynomial $p(x) = ax + b$ is $\ldots \ldots \ldots \ldots$ $(a, b \neq 0)$.

The product of the zeros of a quadratic polynomial $p(x) = 3x^2 + 7x + 4$ is..........
