Question
explore transformations of the basic exponential function \\(y = 2^x\\), shown right. first, change the slider for \\(h\\) to positive values such as 1, 2, or 3. the curve shifts \\(h\\) units right.
if \\(h\\) is instead negative, the curve shifts left.
next, change the slider for \\(k\\) to different positive values. the curve shifts \\(k\\) units up.
if \\(k\\) is instead negative, the graph shifts dropdown

Identify the transformation parameter
Using the Exponential Function Transformations knowledge point
The general transformed exponential function shown in the image is:
\[y = 2^{(x-h)} + k\]
The parameter \(k\) represents the vertical translation of the graph.
Analyze the effect of a negative parameter
Using the Exponential Function Transformations knowledge point
When \(k > 0\), the graph shifts vertically upward by \(k\) units.
When \(k < 0\) (negative), the graph shifts vertically downward by \(|k|\) units.
Therefore, if \(k\) is negative, the graph shifts down.
</reasoning>
<answer>
If \(k\) is instead negative, the graph shifts <blank>down</blank>.
