(b)118 m
(c)48 m
(d)59 m

10.The diagram shows the graph of a function. Which equation could it represent?
(a) $y = x^{3} + 4 x$
(b) $y = x^{3} - 4 x$
(c) $y = - x^{3} + 4 x$
(d) $y = x^{2} - 4 x$
11.The diagram shows the graph of $y = x^{2} - x - 2$ , together with the horizontal line $y = 3$ . Use the graphs to estimate, to 1 decimal place, the two solutions of $x^{2} - x - 2 = 3$ .
