In the context of functions and graphs, which of the following statements best describes a quadratic function?

Step 1: Understand what a function is. A function takes an input (x) and gives an output (f(x)).
Step 2: Learn about polynomial functions. These are functions made up of terms that involve powers of x.
Step 3: Identify the degree of a polynomial. The degree is the highest power of x in the function.
Step 4: Recognize that a quadratic function is a polynomial function of degree two. This means the highest power of x is 2.
Step 5: Know the standard form of a quadratic function, which is f(x) = ax^2 + bx + c, where a, b, and c are constants.
Step 6: Remember that 'a' cannot be zero, because if it were, the function would not be quadratic.

Quadratic Function – A quadratic function is a polynomial function of degree two, typically represented in the form f(x) = ax^2 + bx + c, where a, b, and c are constants and a ≠ 0.
