Question

Determine if the expression 9x^-2 is a polynomial or not. If it is a polynomial, state

the type and degree of the polynomial.

Answer 1

Not a polynomial

Explanation:

Answer 2

9x⁻² is not a polynomial

Explanation:

A polynomial function is a function that involves non-negative integer powers of x such as a quadratic, cubic etc.

A polynomial is a function written in the form of ;

f{x} =aₙxⁿ+aₙ₋₁xⁿ⁻¹+-------+a₂x²+a₁x+a₀

The degree of a polynomial is the highest power of x in the expression

9x⁻² ----in this case, the power is negative thus this is not a polynomial.
