1. Use f(x) to complete the following.

(a) Evaluate fat x = 2, 1, 2, and 3.

(b) Sketch a graph of f. Is f continuous on its domain?

(c) Determine the x-value(s) where f(x) = 3.

2. If f(x) = [2x 1], evaluate f(3.1) and f(2.5).

3. Solve the equation.

51. |2x 5| 1 = 8

52. |3 7x| = 10

53. |6 4x| = 2

54.|9 + x| = |3 2x|
