Question 114289
Graph the given relation and it's inverse on the same coordinate system. Then give an equation of the inverse. 
y=2^x
{{{graph(400,300,-10,10,-10,10,2^x)}}}
------------
Inverse: 
Interchange x and y to get:
x = 2^y
Solve for y:
y = log(base 2) x

Comment: This function will not graph on this site.
----------------
{{{graph(400,300,-10,10,-10,10,(log (x))/(ln(2)))}}}
