Question

when we use function notation, f(#) is asking you to find the output when the input is the given number. We can also consider that an ordered pair can be written as (#,f(#)). With this in mind, explain why f(0) is special. (hint: try writing the ordered pair first-if that doesn't help consider plotting some examples)

Answer 1

Notice that the ordered pair associated to f(0) is:

`(0,f(0))`

These coordinates correspond to the y-intercept.
