Higher June 2017 Paper 3 Q21
21 Here is a sketch of \(\quad y = \mathrm{f}(x) \quad\) where \(\mathrm{f}(x)\) is a quadratic function.
The graph intersects the \(x\)-axis where \(\quad x = -2.5 \quad\) and \(\quad x = 1\)

Not drawn accurately
Circle the solution of \(\;\mathrm{f}(x) \gt 0\) [1 mark]
- \(x \lt -2.5\;\) or \(\;x \gt 1\)
- \(x \gt -2.5\;\) or \(\;x \gt 1\)
- \(-2.5 \lt x \lt 1\)
- \(x \gt -2.5\;\) or \(\;x \lt 1\)
