If Ann correctly factors an expression that is the difference of two perfect squares, her factors could be
(1) (2x + y) (x − 2y)
(3) (x − 4) (x − 4)
(2) (2x + 3y) (2x − 3y)
(4) (2y − 5) (y − 5)

Identify the function that contains the data in the following table: x     -2         0         2         3         5     f(x)     5         3         1         2         4     possible answers: f(x) = |x| + 1 f(x) = |x - 2| f(x) = |x - 2| - 1 f(x) = |x - 2| + 1
