Our free function worksheets are an excellent resource for students! Whether it is recognizing the major function criterion that each input should have only one output or graphing and composing functions, these printable exercises with answer keys are a go-to resource for practice.
Draw a vertical line and see how many times it intersects the graph. If it intersects once, the graph represents a function.
In these PDFs, check the highest exponent: if it's 1, the function is linear; if it's any other exponent, it's nonlinear.
Practice identifying the domain and range of functions, including ordered pairs and finite or infinite graphs in these function worksheets.
Plug input values into the function rule and compute the corresponding output values to complete the function tables.
Evaluate functions by substituting given x-values into function rules and simplifying to find corresponding f(x) values.
Graph linear functions by computing f(x) values, plotting them, and connecting points with a straight line in these function worksheets.
Step up your graphing game with quadratic functions. Find f(x) values for given x-values, plot points, and sketch the parabola.
Refine practice in composing two functions, f(x) and g(x) in these printable worksheets. Simplify and find the composite function value.
