How to Graph a Basic Square Root Function - Study.com

WebThe square root function is f (x) =√x f ( x) = x. The cube root function is f (x)= 3√x f ( x) = x 3. A radical function is a function that is defined by a radical expression. The following are examples of rational functions: f (x) = √2x4 −5 f ( x) = 2 x 4 − 5 ; g(x) = 3√4x−7 g ( x) = 4 x − 7 3 ; h(x) = 7√−8x2 +4 h ( x) = − 8 x 2 + 4 7. WebSince "graphing radical functions" usually means "graphing functions involving square roots", most of the examples in this lesson will deal with square roots.
