which graph represents an exponential function?

Answer:
The graph attached represents an exponential function.
Step-by-step explanation:
An exponential function is represented by a hyperbola which shows some proportionality on the numbers.
The common thing about exponential functions is that they reach infinity.
One example of an exponential function is the graph of [tex]e^{x}[/tex]
The graph is a hyperbolic curve that continues without a definite value.
Another example of such a graph is the graph of :
[tex]y = \frac{1}{x}[/tex]
As the value of y increases, the graph reaches closer and closer to the x- axis but takes forever to reach such a value of intersection.
We say such graphs reach infinity with the y-value.
