- Understand the shape of an exponential function $y = a \cdot b^x$ and identify key intercepts and the horizontal asymptote.
- Explore exponential graph transformations (vertical shift, reflection, dilation).
- Solve real-life problems involving exponential growth and decay.
- Solve depreciation and compound-interest problems.
- Interpret the contextual meaning of the parameters $a$ and $b$ in $y = a \cdot b^x$.
- Use technology to solve basic exponential equations.

- Apply index laws for rational indices, including $a^{m/n} = \sqrt[n]{a^m}$.EXT
- Convert between exponential and logarithmic form: $a^x = y \Leftrightarrow \log_a y = x$.EXT
