WebDec 21, 2024 · A quadratic function is a function of degree two. The graph of a quadratic function is a parabola. The general form of a quadratic function is f(x) = ax2 + bx + c where a, b, and c are real … WebSep 15, 2024 · This means that the domain of any function in the form f(x) = ax2 + bx + c will be ( − ∞, ∞) . The range, however, will depend on the a value and the vertex. If a > 0, then the y-values will include the y-value of the vertex and everything higher. It will be expressed as [f( − b 2a), ∞) .
