What are the main differences between the Greatest Common Factor and the Least Common Multiple of a pair of number? Use the numbers 10 and 15 to show the differences in finding the GCF and LCM. Explain your work.

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
