1. 1Identify the graph of y = −2x + 3: this is a straight line with negative gradient and positive y-intercept, which matches Graph C.
2. 2Identify the graph of y = −1/x: this is a reciprocal graph in the second and fourth quadrants, which matches Graph F.
3. 3Identify the graph of y = tan x°: this is the tangent function with vertical asymptotes and periodic behaviour, which matches Graph D.
4. 4Identify the graph of y = (x + 1)(x − 1)(x − 2): this is a cubic polynomial with roots at x = −1, x = 1, and x = 2, which matches Graph H.
