(a) $y = 1 + cos \pi x$ (b) $y = 1 + 2 sin x$ (c) $y = −5 cos 4x$ Refer to the graph for more information

(a) Where $A = 1$, $B = \pi$, $D = 1$ Hence the equation is $y = 1 + cos \pi x$ (b) Where $A = 2$, $B = 1$, $D = 1$ Hence the equation is $y = 1 + 2 sin x$ (c) Where $A = -5$, $B = 4$, $D = 0$ Hence the equation is $y = −5 cos 4x$ Refer to the graph for more information
