Hello i am doing a cooling experiment and i want to know the following:
y=28.49e^(-0.03890*800) +26.51 (note the 26.51) is not part of the exponential.
What is y? and I was wondering whether this would go ever go through the x axis?
The Attempt at a Solution
I have been putting the info into my calculator and i just can't seem to be able to graph it (TI-84) and from my knowledge of exponentials i don't think that an exponential like this can be below the x axis, but i may very well be wrong.
