The correct option is D The number of zeroes of the polynomial is 0
Since, for every value of x, value of f(x)=7 is constant
∴ it is a constant polynomial.
It can be written as f(x)=7x0 having highest degree as 0.
∴ It is a polynomial of degree 0.
Since, it contains only one term, so it is a monomial.
To find the zeroes of polynomial, we need to put f(x)=0
But for every value of x, f(x)=7
∴ The number of zeroes of the given polynomial is 0.
