Step-by-step explanation:

A. linear equation beacuse...

A polynomial is a function of the form f(x) = anxn + an−1xn−1 + ... + a2x2 + a1x + a0 . The degree of a polynomial is the highest power of x in its expression. Constant (non-zero) polynomials, linear polynomials, quadratics, cubics and quartics are polynomials of degree 0, 1, 2 , 3 and 4 respectively.

Answer:

The function that describes a polynomial of degree 2 is letter B. Quadratic Function.

Explanation:

A quadratic function, which is defined by f(x) = ax2 + bx +c, is an example of a polynomial function in the second degree. While a linear function, which is defined by f(x) = mx + b, is an example of a polynomial function in the first degree.
