The radius of an oil spill is increasing at the rate of 2 miles per hour. Assume the spill remains circular. At what rate is the area of the spill increasing when the radius is 3 miles?

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
