Exercise 1 Page 125

What is different between the first and second equations?

function notation

Practice makes perfect

There are two common ways to write functions:

standard notation
function notation.

Standard notation has x-values as the inputs and y-values as the outputs because those correspond to (x,y)-coordinates on a coordinate plane. Function notation also has x-values as the inputs, but it has f(x) represent the outputs because it is read as f(x)= the value of the function at x. Therefore, f(x)=2x+10 is written in function notation.
