Find the equation of the quadratic function with zeros -1 and 1 and a vertex at (0, -4).
a- y = x2 + 1

b- y = x2 - 1

c- y = 4x2 - 4

d- y = 4x2 + 4x

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?

Which of these equations, when solved, gives a different value of x than the other three? a9.1 = -0.2x + 10 b10 = 9.1 + 0.2x c10 – 0.2x = 9.1 d9.1 – 10 = 0.2x
