Vanessa started with $800 in a bank account that does not earn interest. in the middle of every month, she withdraws
1
4
of the account balance.
which recursive function rule models vanessa’s balance at the end of each month?

an=800⋅an−1and a1=1/4

an=800⋅an−1 and a1=3/4

an=34⋅an−1 and a1=800

an=1/4⋅an−1 and a1=800

An=3/4⋅an−1 and a1=800
34 is 3/4 right?And that is your naswer Vote me brainliest

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.
