Evaluating Piecewise Functions — Easy Worksheet 1
Grade 12 · MathSheets Name: ____________________ Date: __________
Evaluate the function at the given value of x.
How to solve
Compare the given x-value with each condition to choose the correct piece. Substitute x into only that piece and simplify.
Example
f(x) = -x - 3 if x < 4; f(x) = 2x + 2 if x ≥ 4. Find f(1).
