Write the function shown in the graph.
a) f(x) = |x| + 4
b) f(x) =|x| -4
c) f(x) = |x+4|
d) f(x) = |x-4|

Brook states that the distance on the line is 4 units. caleb states that the whole line does not have a distance because it continues on forever. vivian states that the line is 6 units long. which distance did brook measure? which distance did vivian measure?

Find an equation for the linear function which has slope -10 and x-intercept -7

In which direction does the left side of the graph of this function point? f(x) = 3x3 - x2 + 4x - 2
