  1. Use the graph of f(x) = | x − 3 | + 1 in problem 12-26 to solve the equations and inequalities below. It may be helpful to copy the graph onto graph paper first. Homework Help ✎

    1. | x − 3 | + 1 = 1

    2. | x − 3 | + < 4

    3. | x − 3 | + 1 = 3

    4. | x − 3 | + 1 > 2

Remember that with absolute values, there may be 2 possible solutions.

Draw line y = 1 onto the graph and find the intersection point(s).

x = 3

See part (a).
