To write the equation of an exponential function in the form \( f(x) = a(b)^x \), we need two key pieces of information: the initial value (when \( x = 0 \)) and the rate of growth or decay (the base \( b \)).
If you have access to the graph, you can find:
- The value of \( f(0) \), which will give you the parameter \( a \). This is the value of the function when \( x = 0 \).
- Another point on the graph, say \( (x_1, y_1) \), that you can use to determine the base \( b \).
The relationship between \( a \), \( b \), and any point on the graph can be used:
\[ f(x_1) = a(b)^{x_1} \]
Once you have both \( a \) and \( b \), you can substitute them into the equation.
If you can provide specific values or points from the graph, I can help you determine \( a \) and \( b \) more precisely!
