Final answer:
To determine the end behavior, consider the value of the base of the exponential function. If the base is greater than 1, it will increase without bound as x approaches positive infinity, and decrease as x approaches negative infinity. If the base is between 0 and 1, it will approach 0 as x approaches both positive and negative infinity. An exponential function with a positive base will always increase or decrease depending on the sign of the exponent.
Step-by-step explanation:
The given question asks for the end behavior and intervals of increase/decrease of the exponential function. To determine the end behavior, we need to consider the value of the base of the exponential function. If the base is greater than 1, the function will increase without bound as x approaches positive infinity, and decrease without bound as x approaches negative infinity. If the base is between 0 and 1, the function will approach 0 as x approaches both positive and negative infinity. In terms of intervals of increase/decrease, an exponential function with a positive base will always increase or decrease, depending on the sign of the exponent. A positive exponent will result in an increasing function, while a negative exponent will result in a decreasing function. However, if the base is between 0 and 1, the roles of increasing and decreasing will be reversed.
