HanAkoSolo (jamierox4ev3r):

alright, so we want to use some basic function rules here

HanAkoSolo (jamierox4ev3r):

first, let's try graphing a few of these. Want to try the first one for me? If you don't know how, I'll help you with it

OpenStudy (volleyballlover55):

idk how..

HanAkoSolo (jamierox4ev3r):

o alright, that's fine!

HanAkoSolo (jamierox4ev3r):

So remember how we used x and y values in the previous question. We'll do the same thing here. Just thing of the input as (x) values, and the output as (y) values together, you will have a coordinate: (x,y)

OpenStudy (volleyballlover55):

ok...

HanAkoSolo (jamierox4ev3r):

right, so let me draw out the points|dw:1465530569145:dw|

HanAkoSolo (jamierox4ev3r):

For these points, we're going to want to do something called the vertical line test. If the vertical line test is successful, then this is NOT a function.

OpenStudy (volleyballlover55):

ok...

HanAkoSolo (jamierox4ev3r):

So the vertical line test would look like this: |dw:1465530799266:dw|

HanAkoSolo (jamierox4ev3r):

since the vertical line test is successful, the first answer would NOT represent a function

HanAkoSolo (jamierox4ev3r):

If you need help understanding that, think of it this way: you cannot be in two different buildings at the same time, right?
