Linear Functions

Questions

Programming

Coding

A function is like a machine.

It has three main parts: a

domain

, a

codomain

, and the

range

.

The relationship between the domain and range is the function.

What is a function?

Sample Problems:

generator of random numbers

helps information go into a computer and out into a robot or machine!

allows programs to function properly in the object being programmed

simplify a program

Functions are the brain of code! They simplify complicated programs into understandable versions.

y = 25 + 5x

let x = 1

then

y = 25 + 5(1) = 30

let x = 3

then

y = 25 + 5(3) = 40

range

How do they help when coding and programming?

The linear function is the equation to find the slope.

f(5)=-10

A linear function is a straight graphed line.

slope= ?

x=1 y=30

x=2 y=35

x=3 y=40

x=4 y=45
