WebFind the domain: f (x) = x 2 − 4. Solution: Recall that the argument of a square root function must be nonnegative. Therefore, the domain consists of all real numbers for x such that x 2 − 4 is greater than or equal to zero. x 2 − 4 ≥ 0. It should be clear that x 2 − 4 = 0 has two solutions x = ± 2; these are the critical values. WebExample 3 Graph the solution for the linear inequality 2x - y ≥ 4. Solution Step 1: First graph 2x - y = 4. Since the line graph for 2x - y = 4 does not go through the origin (0,0), check that point in the linear inequality. Step 2: …

Web1) Solution is All real numbers. This is demonstrated in this video. You can see that the graph of the 2 inequalities ends up covering the entire number line. 2) The solution is 2 split intervals. For example: x<-2 OR x>0. The solution set is all numbers to the right of -2 combined with all the numbers larger than 0. WebStep 2 Simplify by combining like terms on each side of the inequality. Step 3 Add or subtract quantities to obtain the unknown on one side and the numbers on the other. Step 4 Divide each term of the inequality by the … edege defaults to yahoo search
