The given function is:

$f(x) = -\frac{1}{4} \cdot (3)^{x-1} + 2$

This is an exponential function with the general form:

$f(x) = a \cdot b^{x - h} + k$

Where:

• $a = -\frac{1}{4}$ is the vertical stretch factor.
• $b = 3$ is the base of the exponential function.
• The exponent $x - 1$ indicates a horizontal shift to the right by 1 unit.
• $+2$ indicates a vertical shift upwards by 2 units.

Key characteristics of the function:

1. Horizontal shift: The $x - 1$ shifts the graph 1 unit to the right.
2. Vertical shift: The $+2$ moves the entire graph 2 units upwards.
3. Reflection and scaling: The factor $-\frac{1}{4}$ reflects the graph across the x-axis (due to the negative sign) and scales it by a factor of 1/4, making it flatter.

Would you like to know more about how to graph this function or analyze its behavior at specific points?

Here are 5 follow-up questions:

1. How do we determine the asymptote of this function?
2. What is the domain and range of the function?
3. How does the reflection and stretching impact the graph's shape?
4. Can we calculate the function's value at a specific point, like $x = 2$?
5. How do exponential growth and decay affect real-world applications?

Tip: When working with exponential functions, pay attention to both the base and the exponent shifts—they heavily influence the growth pattern and graph transformation.
