A linear function is a function whose graph is a line in the plane. The characteristic property of these functions is that when the value of the input variable is changed, the change in the output is a constant multiple of the change in the input variable.
Know MoreA linear function is a polynomial function in which the variable x has a degree, which is at most one.
The domain, which is the set of allowed values for x of a linear function, is the entire set of real numbers or whatever field that is in use. This means that any real number can be substituted for x.
Learn more about CalculusA system of linear inequalities is a set of equations of the form f(x) < 0, where f(x) is a function depending on several variables. For the inequalities to be linear, there cannot be any terms in the equations in which variables multiply or divide other variables
Full Answer >A polynomial function is any function that contains more than one monomial, with non-negative exponents, and only contains addition, subtraction, multiplication or division operations. A monomial is a single term consisting of a coefficient and variable, even if the coefficient is one or the variable is 0 and isn't written explicitly.
Full Answer >The inverse function of ln(x) is e^x, where e is the mathematical constant e = 2.718. One can easily check that these two functions are inverses of each other by noting that ln(e^x) = e^ln(x) = 1.
Full Answer >A function is any equation where for any input in the equation, the output yields exactly one value. Typically, the input is called x and the output is called y.
