ECZ 2025 · GCE Paper 1 — Quadratic Functions
The sketch represents the graph of the curve y = x2 − 6x + 5 passing through A, B and C. Find the coordinates of A and B.
- A. A(1, 0) and B(5, 0)
- B. A(0, 1) and B(0, 5)
- C. A(-1, 0) and B(-5, 0)
- D. A(1, 0) and B(6, 0)
Verified working — step 1
A and B are the x-intercepts, where y = 0. Set the curve to zero and factorise.The full step-by-step working and final answer are included with Premium — checked against ECZ marking standards.
