Question

Which of these equations is a quadratic function?

Answer 1

B

Explanation:

Quadratic Function:

A quadratic function is a polynomial function which has a degree of 2, and is generally expressed in standard form:
`ax^2+bx+c\text{ where }a\\e 0`. The degree of a polynomial function can be determined by looking at which term has the largest exponent.

By looking at both options, B would be the correct option as it is a polynomial function with degree 2, while option A is a polynomial function with degree 1, also known as a linear equation.
