Determine range and domain of a function
WebSep 5, 2024 · The range is also determined by the function and the domain. Consider these graphs, and think about what values of y are possible, and what values (if any) are not. In each case, the functions are real-valued: that is, x and f(x) can only be real numbers. Quadratic function, f(x) = x2 − 2x − 3.

WebOct 25, 2024 · 2. Set the denominator equal to zero for fractions with a variable in the denominator. When finding the domain of a fractional function, you must exclude all the x-values that make the denominator equal to zero, because you can never divide by zero. So, write the denominator as an equation and set it equal to 0. [2] WebTo find the domain of a function, consider any restrictions on the input values that would make the function undefined, including dividing by zero, taking the square root of a …
WebIn this example, the domain is {x ≥ 0}, since 0 is the lowest x-value and the arrow indicates the line continues to the right.The boundary number of 0 is included, since the dot is solid. Identify the set of all the y-coordinates in the function’s graph to determine the range.. In this example, the range is {y ≥ -2}, since -2 is the lowest y-value and the arrow indicates … WebApr 11, 2024 · The domain is where the function lies horizontally and the range is where the function lies vertically. In the graph above, notice how there are no values in the domain less than -5 on the left side of the graph. On the right side, the graph keeps going. ... Knowing the properties and graphs of functions helps you find the domain and range.
WebAnother way to identify the domain and range of functions is by using graphs.
