How do you find the domain of a function

David Severin. It does not change the domain, but it would change the formula. For example, if there was a sequence of 16, 8, 4, 2, 1, 1/2, ,,,,, then the number is being cut in half every time. The formula would be a (n)=16 (1/2)^n where n is an integer and n≥0. You could do the same using n-1.

Note: To find the solution set of an equation with a given domain, you first need to plug each value in the domain into the equation to get the respective range values. Create ordered pairs from these values and write them as a set. That set is your answer! Learn it all in this tutorial!Jul 8, 2019 ...

Example 1: For the function f ( x) = 4 x 2 – 2 x + 7, the domain is all real numbers, because no matter what ( x ) value I choose, the equation will always result in a real number. Therefore, the domain is expressed as ( − ∞, ∞). Function. Domain. f ( x) = 4 x 2 – 2 x + 7. The same applies to the vertical extent of the graph, so the domain and range include all real numbers. Figure 18 For the reciprocal function f(x) = 1 x, f ( x) = 1 x, we cannot divide by 0, so we must exclude 0 from the domain. Further, 1 divided by any value can never be 0, so the range also will not include 0. Registering a domain name with Google is a great way to get your website up and running quickly.
