      9 Range of a function Definition. The range of a function f consists of all values f(x)it assumes when x ranges over its domain. Example 1. The range of f(x)=2+ √ x−1 is [2,+∞). To see that, we observe that the natural domain of this function is [1,+∞) since we request that the expression from which we extract the square root is non ...

      Example 1: List the domain and range of the following function. Then find the inverse function and list its domain and range. 𝑓(𝑥)= 1 𝑥+2 As stated above, the denominator of fraction can never equal zero, so in this case 𝑥+2≠0. That means 𝑥≠−2, so the domain is all real numbers except −2. Domain of 𝒇: (−∞,− )∪ ...

      State its domain and range. Solution The function is defined for all real x. The vertex of the function is at (1,1) and therfore the range of the function is all real y ≥ 1. 1.2 Specifying or restricting the domain of a function We sometimes give the rule y = f(x) along with the domain of definition. This domain may not necessarily be the ...

      Domain and Range The domain of a function is the set of values that we are allowed to plug into our function. This set is the x values in a function such as f(x). The range of a function is the set of values that the function assumes. This set is the values that the function shoots out after we plug an x value in. They are the y values.
