Final answer. Step 1/4. Since f (x) and g (x) are both continuous and f (x) ≥ g (x) for all x, there must be some point where f (x) and g (x) intersect. Let's find that point by setting f (x) = g (x) and solving for x. For x ≤ a, both f (x) and g (x) are zero, so they intersect at x = a. For x > a, we have: hairdressers hamilton scotland
