Interpreting Function Notation in Algebra 1

This video tutorial focuses on interpreting function notation, using examples like p(3)=12 to explain how inputs and outputs relate to real-world situations. It covers how graphs can help interpret function notation, using a tub draining example. The video also explains defining functions with rules, creating tables, and graphing functions. It concludes with solving for inputs and outputs using function rules.

What does the expression 'p of 3 equals 12' signify in a functional context?

• The function p outputs 12 when the input is 3.

• The function p has 3 outputs for the input 12.

• The function p decreases by 12 when the input is 3.

• The function p increases by 3 when the input is 12.
