ECZ 2017 · O-Level Paper 1 — Quadratic Functions
The sketch shown below represents a section of the curve y = x(x − 2). Find the coordinates of the points where the curve cuts the x-axis.
- A. (0, 0) and (−2, 0)
- B. (2, 0) and (−2, 0)
- C. (0, 0) and (0, 2)
- D. (0, 0) and (2, 0)
Verified working — step 1
"Cuts the x-axis" means y = 0 - and the curve is already factorised, so the zero rule applies straight away.The full step-by-step working and final answer are included with Premium — checked against ECZ marking standards.
