b (2x−5y)(2x+5y)

c(2x+5iy)(2x+5iy)

d (2x−5iy)(2x−5iy)

Given the following linear function sketch the graph of the function and find the domain and range. ƒ(x) = -5x + 4

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
