1. What is a function?
Functions assign a single unique output for each of their inputs. In this video, Sal gives many examples of various kinds of functions.
4. Function notation example
Sal uses function notation to help Frank figure out how much water he can put in his balloon.
6. Equations vs. functions
Jesse Roe and Sal talk about the difference between equations and functions
7. Manipulating formulas: temperature
Sal takes the formula for converting from Fahrenheit temperature to Celsius, and solves it for F so it serves to convert from Celsius to Fahrenheit.
8. Function rules from equations
Create functions that match one variable to the other in a two-variable equation.
9. Comparing linear functions
Sal is given the formula of a linear function and the graph of another, and is asked to determine which function increases faster.
10. Comparing linear functions (example 2)
Sal is given a table of values of a linear function and four linear graphs, and is asked to determine which graph has the same rate of change as the function represented in the table.
11. Comparing linear functions (example 3)
Sal is given a table of values of a linear function and four linear graphs, and is asked to determine which graph increases faster than the function represented in the table.
