Graphing Lines in Traditional Algebra 1

The video tutorial covers graphing linear functions, introducing the transition from traditional y=mx+b notation to function notation f(x). It explains the roles of independent and dependent variables, demonstrates graphing techniques using the new notation, and discusses real-world applications. The tutorial emphasizes understanding function notation for solving equations and graphing, providing examples and practice problems to reinforce learning.

What is the new notation introduced for graphing linear functions?

• f(x) = 2x + 1

• h(x) = x^2 + 1

• g(x) = 3x + 2

• y = mx + b
