Find equations for exponential functions that pass through the given pair of points. (Round all coefficients to 4 decimal places if necessary.)
(2, 3) and (3, 4)

y= K e^ax
3=Ke^2a
4=Ke^3a
divide the equations
3/4= e^(2a3a)
take the ln of each side
ln .75 = 5a
solve for a. Then go back,either equation, solve for K
