The function f(x) is shown in the graph.
anzhelika [568]

<h3>How to determine the function type?</h3>

From the graph, we have the following highlights:

  • Initially, when x increases; y seem not to increase
  • Then, x and y increase at the same time
  • Finally, y increase and x seem not to increase

The above is the description of an exponential function

Hence, the function that describes the graph is an exponential function
