WebThe domain for g (x)=√ (3−x) is up to and including 3: So the new domain (after adding or whatever) is from 0 to 3: If we choose any other value, then one or the other part of the new function won't work. In other words we want to find where the two domains intersect. Note: we can put this whole idea into one line using Set Builder Notation: WebTo find the domain of a function, we remember the following: The denominator of a fraction cannot be equal to zero. The number under a square root sign cannot be negative. Therefore, the domain of a function is found by looking for the values of the independent variable (usually x) that we can use. philishave 6851 https://login-informatica.com
