We use the first point given (0, 14) to solve <em>a </em>in terms of <em>b</em>. We have

We use the second point given (3,3024) to solve for the value of <em>b</em>,

Substitute the value of <em>a</em> solved by the equation above on the equation above and solve
![\begin{gathered} 3024=14b^3 \\ b=\sqrt[3]{216} \\ b=6 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%203024%3D14b%5E3%20%5C%5C%20b%3D%5Csqrt%5B3%5D%7B216%7D%20%5C%5C%20b%3D6%20%5Cend%7Bgathered%7D)
Hence, the exponential function is written as
