MA T H 0003 Question 2 A. Given the functiony : 3x2 + 12x 1. i. Express y in the form a (x + h)2 + k, Where a, h and k are real numbers (3 marks) ii. Determine the values of x for which y = O (4 marks) iii. Find the y-intercept (2 marks) iv. Hence, sketch the graph of the function y : 3x2 + 12x l (6 marks) B. In the diagram below, angle ABD : x 80 and angle DBC : 2x + 20. D 2 + 2' A A x C B Figure 2 Determine the: i. value of x (3 marks) ii. measure of angle ABD (1 mark) iii. measure of angle DEC (1 mark) (Total 20 marks) 21/08 The Council of Community Colleges of Jamaica Page 3
