Question 851422: Please help me to understand how to do this problem.
I have tried for 25 minutes to solve this problem and I've hit the wall. I've looked it up in my textbook...googled Khan Academy videos, etc...to no avail.
Even though the problem says to provide a graph---I really don't need the graph because I know that it's decaying, however, if you wish to provide one that would be great.
Here's the problem:
Graph f(x)=10e^-0.2x for -5< or equal to x > or equal to 15
FIND f(10) and f(-10)

I would really love to know how to do the steps!
Thank you in advance!
Warm regards,
JD
