What are the period and phase shift for f(x) = −4 tan(x − π)?
a) period: π; phase shift: x = pi over two
b) period: π; phase shift: x = π
c) period: 2π; phase shift: x = pi over two
d) period: 2π; phase shift: x = π

You are constructing a histogram for scores that range from 70 to 100 in whole points. frequencies range from 3 to 10; that is, every whole-point score between 60 and 100 occurs at least 3 times, and at least one score occurs 10 times. which of these would probably be the best range and size for the score intervals along the x-axis?
