Math Problem Statement
Find an equation for the exponential function graphed.
Solution
The graph shows an exponential function , and it passes through the point . Based on this, we can derive the general form of the equation of the function.
General form of an exponential function:
The general form of an exponential function is:
Where:
- is the initial value (the -intercept, when ),
- is the base of the exponential function.
Step 1: Use the given point
From the graph, we know the function passes through . This tells us that when , . Plugging this into the general equation:
So, .
Step 2: Determine
Next, we need to determine . From the graph, it appears that the function is increasing exponentially, meaning . However, we don't have another exact point to directly calculate , but we can hypothesize that the base could be , which is a common base for exponential functions.
So, the equation of the exponential function is:
This is a reasonable assumption based on the graph's shape and the common use of in exponential growth problems.

Tip:
When analyzing exponential functions, look for points where to quickly determine the initial value, and use other points to find the base.
