Point M is on line segment \overline{LN} LN . Given MN=3x, MN=3x, LN=4x+9,LN=4x+9, and LM=2x+7,LM=2x+7, determine the numerical length of \overline{LM}. LM .

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
