To evaluate a piecewise function: 1. Determine which interval of the domain in which the value falls. 2. Replace each x with the number. 3. Simplify, using order of operations. Example: Evaluate the piecewise function. x² x < -2 -2 ≤ x < 2 2x + 4 f(x) = 3 x ≥ 2 10. f() 11. f(-4) LAB #4 if if if Pg. 3 12. f()
