29 Here is the graph of \(\;y = \mathrm{f}(x)\;\) where \(\mathrm{f}(x)\) is a quadratic function.

Graph of an n-shaped parabola for x from about −4.4 to 3.3, crossing the x-axis at about −3.3 and 2, crossing the y-axis at 20, with maximum about 21 near x = −0.6

Write down all the integer solutions of \(\;\mathrm{f}(x) \geqslant 0\) [2 marks]
