Zack's biology lab group is studying how quickly bacteria grow when exposed to sunlight. At the beginning of the experiment, Zack looked at the sample under a microscope and counted 5 bacteria. After the sample was exposed to sunlight for one hour, Zack looked again and counted 35 bacteria. Write an exponential equation in the form \( y=a(b)^{x} \) that can model the number of bacteria, \( y \), after \( x \) hours in sunlight. Use whole numbers, decimals, or simplified fractions for the values of \( a \) and \( b \).
