WebThe domain of a function is the set of all possible inputs for the function. For example, the domain of f(x)=x² is all real numbers, and the domain of g(x)=1/x is all real numbers except for x=0. We can also define special functions whose domains are more limited. WebNov 16, 2024 · Recall that domains of functions of a single variable, \(y = f\left( x \right)\), consisted of all the values of \(x\) that we could plug into the function and get back a real number.

WebRules of Finding Domain of a Function. Domain of any polynomial (linear, quadratic, cubic, etc) function is ℝ (all real numbers). Domain of a square root function √x is x ≥ 0. Domain of an exponential function is ℝ. Domain of logarithmic function is x>0. To find the domain of a rational function y = f(x), set the denominator ≠ 0. WebDec 28, 2024 · Figure 12.1. 1: Illustrating the domain of f ( x, y) in Example 12.1.2. The range is the set of all possible output values. The square-root ensures that all output is ≥ 0. Since the x and y terms are squared, then subtracted, inside the square-root, the largest output value comes at x = 0, y = 0: f ( 0, 0) = 1.
