A Function Calculator is a free online tool that displays the graph of the given function. There are other ways of solving a quadratic equation instead of using the quadratic formula, such as factoring (direct factoring, grouping, AC method), completing the square, graphing and others. To help you understand this notation, letâs look at a couple of examples. To evaluate a function is to: Replace its variable with a given number or expression. Just replace the variable "x" with "5": comments below. This video shows you how to evaluate trigonometric functions without a calculator. In elementary algebra, the quadratic formula is a formula that provides the solution(s) to a quadratic equation. Function formula can be entered using expression with math operations, numeric constants and functions. Also, be careful when you write fractions: 1/x^2 ln(x) is `1/x^2 ln(x)`, and 1/(x^2 ln(x)) is `1/(x^2 ln(x))`.
