- The quadratic and cubic functions are power functions with whole number powers f(x) = x2 and f(x) = x3. The reciprocal and reciprocal squared functions are power functions with negative whole number powers because they can be written as f(x) = x − 1 and f(x) = x − 2.
Feb 26, 2024 · Construct the equation, sketch the graph, and find the horizontal and vertical asymptotes of the reciprocal squared function that has been shifted right 3 units and down 4 units. Answer. Graph 1/x and 1/x^2 and translations of those graphs.
May 9, 2022 · The reciprocal and reciprocal squared functions are power functions with negative whole number powers because they can be written as \(f(x)=x^{−1}\) and \(f(x)=x^{−2}\). The square and cube root functions are power functions with fractional powers because they can be written as \(f(x)=x^{1/2}\) or \(f(x)=x^{1/3}\).

A power function is a function with a single term that is the product of a real number, a coefficient, and a variable raised to a fixed real number. (A number that multiplies a variable raised to an exponent is known as a coefficient.) As an example, consider functions for area or volume. The function for the area of a circle with radius r is.
