(a) Copy and complete the table of values for \(y = 1 - 4\cos x\).

x	0°	30°	60°	90°	120°	150°	180°	210°	240°	270°	300°
y	-3.0			1.0				4.5			-1.0

(b) Using a scale of 2cm to 30° on the x- axis and 2cm to 1 unit on the y- axis, draw the graph of \(y = 1 - 4\cos x\) for \(0° \leq x \leq 360°\).

(c) Use the graph to : (i) solve the equation \(1 - 4\cos x = 0\) ; (ii) find the value of y when x = 105° ; (iii) find x when y = 1.5.
