Beginner Topic 5 of 51 Math for Computing
Functions and Graphs
Visualizing relationships between quantities.
How it works
A function maps inputs to outputs; graphs reveal growth, intercepts and symmetry; composition and inverses combine functions.
Where it is used
Modeling relationships.
Common pitfall
Domain restrictions such as division by zero.
