Answer:
The graph is shown below.
Explanation:
Given:
The exponential function to graph is given as:

In order to graph the above function, we first find some points on it by taking random values of 'x'.
x -2 -1 0 0.5
f(x) 0.018 0.135 1 2.718
Now, the points on the graph are:
(-2, 0.018), (-1, 0.135), (0, 1), and (0.5, 2.718).
Now, we plot these points on the graph.
Next, we find the horizontal asymptotes. For that, we find the limit with x tending to negative infinity. This gives,

Therefore,
or the x-axis is the horizontal asymptote. As exponential functions are increasing functions, so for 'x' tending to positive infinity, the function will also tend towards positive infinity.
Now, we draw a smooth curve passing through the given points and continuing the graph parallel to x-axis for greater values of x along the negative x-axis.
The graph is shown below.
