![]() Our calculator provides accurate results. Our calculator can handle a wide range of functions to meet your requirements. It features an intuitive interface that allows both beginners and experts to navigate with ease. Our calculator is designed with user-friendliness in mind. This function exhibits exponential growth or decay. An exponential function has the following form: $$f(x)=a\cdot b^x $$ This function represents a parabolic curve.Įxponential Function. A quadratic function has the following form: $$f(x)=ax^2+bx+c $$ This function represents a straight line on a graph, where $$$m $$$ is the slope, and $$$b $$$ is the y-intercept. A linear function has the following form: $$f(x)=mx+b $$ This formula can be very simple, for example, $$$f(x)=x $$$, or very complex, for example, $$$f(x,y,z)=\frac $$$ (a multivariable function). What Is the Mathematical Expression of a Function?Ī function is often expressed using a formula or rule that describes how the input values are transformed into output values. It represents the dependent variable's value corresponding to the given input. Output: The output of a function is the result of applying the function to the input value(s).It's the value for which you want to determine the corresponding output. Input: The input of a function is the value of its variable you provide as an argument to the function.It represents the values that the function actually produces. Range: The range of a function is the set of all actual output values.It represents the values that the function can produce. Codomain: The codomain of a function is the set of all possible output values. ![]() It defines where the function is defined or valid. Domain: The domain of a function is the set of all possible input values.By the way, it is not one-to-one, since there are two elements, namely $$$-2 $$$ and $$$2 $$$, that give $$$4 $$$. In the notation $$$f(x) $$$ $$$f $$$ is the function symbol and $$$x $$$ represents the input variable.įor example, $$$f(x)=x^2 $$$ is a quadratic function. The function is called one-to-one if no two elements from its domain give the same element from the range.įunctions are typically denoted using various notations. The set of such values forms the output set (range, codomain). In mathematics, a function is a formula that, for every value from the input set (domain), produces some value. The calculator will quickly display the properties of the function. If necessary, enter the interval which you are interested in.Ĭlick the "Calculate" button to start the process. How to Use the Function Calculator?Įnter the function you want to analyze. Easily explore functions by examining their parity, domain, range, intercepts, critical points, intervals of increase/decrease, local and global extrema, concavity intervals, inflection points, derivatives, integrals, asymptotes, and so on. The Function Calculator is a tool that allows you to many properties of functions. maker from which the best compromise alternative should emerge, one extracts the kernel of the graph.
