Enter the equation into Y=
Hit GRAPH. Be sure the
graph is viewable in the graphing window. Adjust the
WINDOW if needed.
From the HOME screen, hit the MATH key.
Choose either #6 fMin or
The parameters for fMin
and fMax the same:
fMin(expression, variable, left
bound, right bound)
Be careful: The
answer from fMin is the X-coordinate
where the minimum occurs. It is not the actual y-value
minimum. You must then calculate the y-value.
Again, remember that the answer from
fMax is the X-coordinate where the maximum
occurs. You must then calculate the y-value.
