Mathematics for IGCSE & O level - Sketching Curves (Section 3 - No. 28)
What happens to the graph of \(y = 2^x\) if the equation becomes \(y = 2^{x-2}\)?
The graph shifts 2 units to the left.
The graph shifts 2 units to the right.
The graph shifts 2 units upwards.
The graph shifts 2 units downwards.
Explanation
Subtracting from the exponent of the base translates the graph along the x-axis. x-2 means a shift to the right by 2 units.
