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

9x⁻²  is not a polynomial

Step-by-step 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.

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8
