Transformations:
![y=a*5^(bx-h)+k](https://img.qammunity.org/2023/formulas/mathematics/college/xpp74jrbh4wi8pzwbdqd1ziut9d2c9hdo9.png)
If a is negative it is a reflection across x-axis
If b is negative (change of symbol of x variable) it is a reflection across the y-axis
If h is positive it is a translation h units to the left
If h is negative it is a translation h units to the right
If k is positive it is a translation k units up
If k is negative it is a translation k units down
Given expressions and corresponding transfomation are:
1.
