Mathematics for IGCSE & O level - Sketching Curves (Section 1 - No. 13)
If an exponential function is of the form y = a^(x) where 0 < a < 1, what can you conclude about its graph?
The graph increases.
The graph is linear.
The graph decreases.
The graph is a parabola.
Spiegazione
When 0 < a < 1, the graph of y = a^x represents exponential decay, meaning it decreases as x increases.
