Exploring Function Notation and Graphs

The video introduces the Hurley Calculus Channel and covers function notation, explaining how the function name and variable choice are represented. It demonstrates how to translate functions into graphs by plotting ordered pairs on a coordinate plane. The video also discusses the interchangeability of f(x) and y notation in equations, providing a foundational understanding of these concepts.

What is the main topic of the video?

• Algebraic equations

• Function notation and graphs

• Trigonometric functions

• Calculus derivatives
