(a) Copy and complete the table of values for the relation \(y = 2 \sin x + 1\)

x	0°	30°	60°	90°	120°	150°	180°	210°	240°	270°
y	1.0				2.7			0.0	-0.7

(b) Using scales of 2 cm to 30° on  the x- axis and 2 cm to 1 unit on the y- axis, draw the graph of \(y = 2 \sin x + 1, 0° \leq x \leq 270°\).

(c) Use the graph to find the values of x for which \(\sin x = \frac{1}{4}\).
