WebFind the domain of the function f defined by: Solution to Example 5 Let us first find the values that makes the denominator equal to zerox3- x = 0 Factor the expression on the left hand side of the equationx(x2- 1) = 0 x(x + 1)(x - 1) = 0 Solve the above equation to obtain the solution set as follows:x = 0, x = 1 and x = -1 WebThe function will be defined for all real numbers except when the denominator equals 0. (We cannot divide by 0 after all.) The easiest way to determine when the denominator equals 0 is to factor the quadratic equation. g (x) = (x + 1) / ( (x - 5) * (x + 3)) As you can see, the … A domain is the set of all of the inputs over which the function is defined. So if thi… A coordinate plane. The x- and y-axes both scale by one.

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
