Intervals for piecewise functions are usually written in set-builder notation. True or False

The step function g(x) is defined as shown. what is the range of g(x)? ***answer choices in picture.

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
