A graph can be modeled by several functions such as exponential function, logarithm functions, linear functions, quadratic functions, etc.
- The graph is neither an exponential function, nor a logarithmic function
- The y-intercept is 600
The function type
An exponential function and a logarithmic function would either increase through its interval or decrease through its interval.
These functions would not increase and then decrease or decrease and then increase at different intervals.
From the attached graph, we can see that the graph increases and decreases at several intervals.
Because of this changes in the graph behavior, the graph cannot represent an exponential function or a logarithmic function.
The y-intercept
The graph cross the y-axis at y = 600.
Hence, the y-intercept is 600
