Mario deposits $300 in a savings account over the course of a year. he deposits money into the account throughout t next year until his balance is doubled. the next year he does the same and deposits money into the account until his previous year's balance is doubled assume that this trend continues and his account does not earn interest. consider his initial balance to be year one. what explicit formula can be used to determine the balance of his savings account at the end of n years?

 The answer is an=2⋅ 300^n−1.

see attached

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph

option: d is the correct answer.

d) none of the above.

step-by-step explanation:

clearly from the figure attached to the question we could see that there is no shape given. hence without any shape given in the figure and after rotation we can't obtained a square pyramid.

since, to obtain a image we need a proper figure of the pre-image so that it can be transformed.

hence, the correct answer is:

d) none of the above.
