The flash unit on a camera operates by storing charge on a capacitor and releasing it suddenly when the flash is set off.?

The data in the table below describe the charge remaining on the capacitor (measured in microcoulombs, μC) at time t (measured in seconds).
Use a graphing calculator or a computer to find an exponential model for the charge.

t Q
0.00 100.07
0.02 86.15
0.04 74.17
0.06 63.86
0.08 54.97
