What are the domain and range of a function? What are the domain and range of the graph of a function? In this lesson, learn the definition of domain and range as it applies to functions as well as how it applies to graphs of functions. Moreover, there will be several examples present...
Find the domain and range of the functionf(x)=x+2x2−9,\displaystyle f{{\left({x}\right)}}=\frac{\sqrt{{{x}+{2}}}{{{x}^{2}-{9}}},f(x)=x2−9x+2,without using a graph. Solution In the numerator (top) of this fraction, we have a square root. To make su...
If a function is present in one of the functions mentioned in the above rules, we can straight away apply the rules and find its range. Otherwise, we can graph it and look at the y-values the graph covers to calculate range. Here are some examples: Example 1:To calculate the range of...
A graph of ff also helps in interpreting the range of a function. Below is shown the graph of function ff given above. Note the lowest point in the graph has a y(=f(x))y(=f(x)) value of - 2. Matched Problem 4Find the range of function ff defined by: f(x)=x2+3f(x)=x2...
