WebFind the domain of function f defined by f (x) = log 3 (x - 1) Solution to Example 1 f (x) can take real values if the argument of log 3 (x - 1) which is x - 1 is positive. Hence the condition on the argument x - 1 > 0 Solve the above inequality for x to obtain the domain: x > 1 or in interval form (1 , ∞) Matched Problem 1 WebIntroducing intervals, which are bounded sets of numbers and are very useful when describing domain and range. We can use interval notation to show that a value falls between two endpoints. For example, -3≤x≤2, [-3,2], and {x∈ℝ -3≤x≤2} all mean that x is between -3 and 2 and could be either endpoint.
