The expression \( f(1) = f(2) \) indicates that the number of stickers Brenda receives on day 1 is the same as the number of stickers she receives on day 2. This could mean that she brushed her teeth the same number of times on both days, or it could be that regardless of how many times she brushed, the reward system (the number of stickers per day) was identical for those two days. In other words, Brenda's performance or achievement in terms of tooth brushing on day 1 and day 2 was equal in terms of stickers earned.
Little Brenda just started brushing her teeth on her own. Every time she does, she gets a sticker. The function f(x) gives the number of stickers Brenda gets on day x.
What does f(1)=f(2) tell you?
