The left end approaches infinity, and the right end approaches 0.
The image contains a question about the end behavior of a given function:
This is an exponential decay function because the base of the exponent, 0.75, is between 0 and 1. Here's how to determine the end behavior:
- As
(to the right),
approaches 0, because any number less than 1 raised to an increasingly large exponent will get closer and closer to 0. So, the right end of the graph of
will approach 0.
- As
(to the left),
grows without bound because raising a number between 0 and 1 to a negative exponent results in a fraction with a numerator of 1 and a very small denominator, which becomes a very large number. Therefore, the left end of the graph will approach infinity.
So, the complete statement would be:
The left end approaches infinity, and the right end approaches 0.
