Easy -2.0 This is a basic recognition question requiring only recall of the defining property that exponential functions y = a^x (a > 0) are always positive. It's a 1-mark multiple choice question with no calculation or problem-solving required—students simply need to identify which graph goes below the x-axis.
One of the graphs shown below **cannot** have an equation of the form
$$y = a^x \quad \text{where } a > 0$$
Identify this graph.
Tick (\(\checkmark\)) one box.
