1) If you deposited $10,000 into a bank savings account on your 18th birthdaysaid account yielded 3% compounded annually, how much money would be in your account on your 58th birthday? 2)What would your answer be if the interest was compounded monthly versus
annually?

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.
