How do you use the graphing calculator to solve #2^(-x-3)=3^(x+1)#?
We can plot both functions on the same plot and see where they intersect.
Socratic doesn't have a good way to plot two functions as far as I know, so you can see a good plot here.
We could also do this analytically using logarithms:
which is exactly where we saw it in the above.
