Equation of an exponential function

[Math_Junkie]

How would I go about finding the equation to the following function:

I know that the base is an exponential function, f(x) = Something[sup:2zhpouuv]x[/sup:2zhpouuv].

Any help/suggestions?

We have $\displaystyle y=a\cdot b^{x}$

$\displaystyle 24=a\cdot b^{3}$

$\displaystyle 6=a\cdot b^{1}$

solve for a and b.
