Ease of Use:

Overview:: This site offers a graphing tool for functions, and the site supports graphing up to 5 functions together.
Type of Material:: Simulation
Recommended Uses:: This site is suitable for use in classrooms, for homework assignments, individual learning, or group exploration in mathematics-related courses.
Technical Requirements:: Any browser
Identify Major Learning Goals:: The major learning goals to help students to use this tool to visually explore and understand how different types of functions behave by graphing them and seeing how changes to their equations affect their shape and position.
Target Student Population:: Pre-Calculus, College Algebra, and Calculus I.
Prerequisite Knowledge or Skills:: Students should have: Understanding of basic functions and their notation and Graphs, and Some exposure to graph transformations (shifts, stretches, reflections)

Rating:
Strengths:: The module is highly accessible and presents concepts with clarity and simplicity. It covers a wide range of function types and graph behaviors, all while staying visually clean. The inclusion of a parameter slider adds a strong dynamic element to help students grasp how functions change.
Concerns:: The site does not explain mathematical theory in-depth—students may require outside context or instruction.

Rating:
Strengths:: The tool is great for reinforcing graphing skills and seeing real-time results. It promotes exploration, helps students test hypotheses visually, and supports differentiated instruction for visual learners.
Concerns:: The tool lacks explicit learning goals and assumes prior familiarity with functions and transformations. Without guided prompts or lesson structure, it may not stand alone as a full learning module.

Rating:
Strengths:: The tool is very clean layout and intuitive controls. Students can input functions and immediately see visual output, which makes for a smooth user experience.
Concerns:: Typing complicated functions can be difficult for some students, especially those unfamiliar with syntax; the tool does not provide an on-screen keypad or input assistance, which could help with accessibility and ease of use.
