Graphing Radical Functions
Radical functions are functions that involve square roots or other radical expressions. They have unique characteristics that distinguish them from other types of functions.
Key Features of Radical Functions, Graphing radical functions quiz part 2
- Domain: The domain of a radical function is the set of all values for which the function is defined. For square root functions, the domain is typically all non-negative real numbers.
- Range: The range of a radical function is the set of all possible output values. For square root functions, the range is typically all non-negative real numbers.
- Asymptotes: Vertical asymptotes occur at the values where the radicand is zero. Horizontal asymptotes may occur at the limit of the function as x approaches infinity.
- Intervals of Increase and Decrease: Radical functions increase on intervals where the radicand is positive and decrease on intervals where the radicand is negative.
Examples of Radical Functions
Consider the function f(x) = √(x – 2). The domain of this function is all values of x greater than or equal to 2. The range is all values of y greater than or equal to 0. The graph of this function has a vertical asymptote at x = 2 and increases on the interval [2, ∞).
