Write A Function Describing A Relationship
Muhtasari
Real problems rarely arrive as equations. They arrive as descriptions: a taxi charges a fixed fee plus a rate per mile, a tank drains at a steady rate, a savings balance grows each year. Turning such a description into a function is one of the most useful skills in all of algebra, because once you have the function you can answer any question about the situation.
In this lesson you will write a function that describes the relationship between two quantities. You will identify the input and the output, capture any fixed amount and any rate of change, and assemble them into a clear rule in function notation.
Malengo
- Write a function that describes a relationship between two quantities.
