The question, in short
Match three given equations, y = x² + 1, y = 2ˣ and y = 1/x, to the correct lettered sketch among six curves A to F.
Summarised in our own words. Use the official paper for the exact wording and the diagram.
Solution · 3 marks
- 1y = x² + 1: U-shaped parabola with minimum at (0, 1) → E
- 2y = 2ˣ: exponential growth, crosses y-axis at 1, above x-axis → C
- 3y = 1/x: two branches in 1st and 3rd quadrants → A
