Mason stands on the 5^\text{th}5 th
5, start superscript, start text, t, h, end text, end superscript step of a vertical ladder. The ladder has 151515 steps, and the height difference between consecutive steps is 0.5\text{ m}0.5 m0, point, 5, start text, space, m, end text.
h(n)h(n)h, left parenthesis, n, right parenthesis models the height above the ground of Mason's feet (in \text{m}mstart text, m, end text) after moving nnn steps (if Mason went down the ladder, nnn is negative.)
