Assessment: WAEC SSCE - General Mathematics - 2002 (Objective) Subject: General Mathematics

Question 1 Report


Which of the following is represented by the above sketch?

Answer Details
The given sketch is a quadratic function graph. From the graph, we can see that the parabola intersects the x-axis at two points which are (-3, 0) and (2, 0). Therefore, the roots or zeros of the quadratic function are -3 and 2. By comparing the options given, we can see that only option B, y = x2 - x - 6, has roots of -3 and 2. Thus, option B is the correct answer.
