The number of bacteria in a petri dish increases by 19% every hour. if there were initially 300 bacteria placed in the petri dish, write a function that can be used to determine the number of bacteria in the petri dish in exactly hours.

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.
