# Math Help - Finding maximum and minimum values for exponential equation without using Calculus

1. ## Finding maximum and minimum values for exponential equation without using Calculus

How do you find the maximum and minimum values for the given exponential equation on the given interval without using calculus(derivatives)

y = 100(0.85)^t , for 0 <= t <= 5

an exponential function of the form $y = a \cdot b^t$ where $a > 0$ and $0 < b < 1$ is a strictly decreasing function.

so, where would the max and min be located?

3. Max = (0,100)

Min = (5,44.4)

4. Very good!
