Im giving 99 points for this question. this is only because it determines whether or not i'll have an a in algebra 1 or a d in algebra 1. i've used every single resource imaginable, with no luck, and is my last hope. ive already answered some of the question, i just need someone to check and finish it. here it is:

belinda wants to invest $1000. the table below shows the value of her investment under two different options for three different years:

number of years 1 2 3
option 1 (amount in dollars) 1100 1200 1300
option 2 (amount in dollars) 1100 1210 1331

part a: what type of function, linear or exponential, can be used to describe the value of the investment after a fixed number of years using option 1 and option 2? explain your answer. (2 points)

part b: write one function for each option to describe the value of the investment f(n), in dollars, after n years. (4 points)

part c: belinda wants to invest in an option that would to increase her investment value by the greatest amount in 20 years. will there be any significant difference in the value of belinda's investment after 20 years if she uses option 2 over option 1? explain your answer, and show the investment value after 20 years for each option. (4 points)

answers

part a: option 1 is linear since it is in increasing by a constant amount each year option 2 is exponential since it is increasing by a ratio each year

part b: option 1: f(n)= 100n +1000
option 2: g(n) = 110n + 10
