The implied domain is the set of all real numbers for which the expression is defined. The domain excludes x-values that result in division by zero. To find these excluded x-values, first set the denominator of the function equal to 0. Then factor the left side of the equation, set each factor equal to 0, and solve to find the values of x that result in division by zero. Doing so gives the following result. x² - 3x = 0 x Your answer cannot be understood or graded. More Information = 0 x(x-[ The first factor, x, gives the zero x = 0. The other factor gives the following zero. (x - [ = 0 X = The domain is therefore all real numbers except x = 0 and x =
