In studying lynchings between 1899 and 1946, psychologist Brian Mullin found that the size of a lynch mob relative to the number of victims predicted the level of brutality. He developed a formula for the other-total ratio (y) that predicts the level of self-attentiveness of people in a crowd of size x with 1 victim.
y = 1 / x + 1
The lower the value of y, the more likely an individual is to be influenced by "mob psychology." Graph this function; use positive integers as its domain?
