Point Of intersection between two plotted functions

Let your 2 functions be f(x) and g(x).  Then you have to solve the
equation f(x) = g(x).

For some functions it will be easier to determine intervals of the
real line where f(x)-g(x) > 0 and where f(x)-g(x) < 0 and to find an
interval in which the 2 intersect, which would probably be good enough
for plotting.

How straightforward any of this is depends entirely on the nature of
your functions.
