Question 2 A. i. Write x2 +5x-14 in the form a(x+ h) + k where a, h and k are constants. ii. Sketch the graph of f (x) = x3 +5x-14. Write the coordinates of the: 1. y-intercept 2. minimum point B. A ray OC stands on a line AOB. Determine the value of x, if ZCOB = (2x +3)" and ZCOA = (3x+7)". Hence determine the measures of ZCOA and ZCOB. C. The four angles of a quadrilateral are in the ratio 2:3:4:6. Determine the measure of each angle. D. In the rectangle ABCD, angle ODC = 350. Determine the angles labelled a, b, c, and d. 35 E. The diagram below, not drawn to scale, shows a circle with centre O. The points U, V, Wand X lie on the circumference of the circle. Angle VOX = 110', angle VUX = a' and angle VWX = b .
