Thomas and his friends plan to collect cans for 10 days. Which statement describes why the relation between the number of days and the cans collected is a function? Select each correct answer. Each day corresponds to a unique amount of cans in this relation. The graph of the relation would pass the horizontal line test. Each amount of cans corresponds to a unique day in this relation. The graph of the relation would pass the vertical line test.

Answer 1

When he first starts with two cans he id doubling the number by multiplying the number by the power of 2. so every day it would be 2,4,8,16,32,64,128,256,512,1024. So they would have 1024 cans on the tenth day.
