How to solve modulus inequalities and equations. also know as solving absolute value inequalities. modulus inequalities revision questions handout. absolut. Step 1: sketch the graphs of y = |x^2 4| and y = 3 on the same pair of axes. step 2: work out the ranges of x for which f (x) \geq 0 and f (x) < 0 from the graph: x^2 4 \geq 0 for x \leq 2 or x \geq 2. and x^2 4 < 0 for 2 < x < 2. step 3: use step 2 to write 2 new equations, one that holds for each range of x:. Step 1 sketch the graphs including any modulus (reflected) parts. (see modulus functions – sketching graphs) step 2 locate the graph intersections. step 3 solve the appropriate equation (s) or inequality. for the two possible equations are and.
