<h2>Explanation:</h2><h3>1. Are exponential function one to one. How can you tell?</h3>- A function
is one-to-one if each value of
corresponds to exactly one value of
.
To demonstrate this, we take the Horizontal Line Test that states:
<em>A function has an inverse function if and only if there is no any horizontal line that intersects the graph of
at more than one point.</em>
As you can see in the first figure, the horizontal line (the green one) intersects the graph of the exponential function
(the red one) in just one point. If you take every horizontal line
with
any real number, you will find that every line intersects the exponential function in just one point. Therefore, this function is one-to-one
Another important thing is that:
- A function has an inverse function if and only if is one-to-one.
As we have demonstrated that exponential functions are one-to-one by Horizontal Line Test, then we conclude exponential functions have inverse functions. The domain of the inverse function is the range of the original one and the range of the inverse function is the domain of the original one. The inverse of is
whose graph is the second figure below.
