2) We can check if relations are functions by: making sure each input maps to exactly one output and the vertical line test.
3) A picture, graph, diagram, or equation!]]> 2018-03-19 13:57:46 UTC https://padlet.com/sushakov1/xfzb3sb3lrw4/wish/243498654 https://padlet.com/sushakov1/xfzb3sb3lrw4/wish/243501613 1) With functions you can expect the same pattern which is the same with machines, but with relations you can't always expect the same thing.
2) if each input has only one line connected to it then the outputs are a function of the inputs.

2)you can use the verticle line test

2) If you draw a verticle line and it goes through two points it's a relation
3) Graph the relation as a function.]]> 2018-03-19 14:01:17 UTC https://padlet.com/sushakov1/xfzb3sb3lrw4/wish/243501920 21kuhnc https://padlet.com/sushakov1/xfzb3sb3lrw4/wish/243502111 1) Functions are like machines because there is always one output. Relations are not, because of there being more than one output for the input.
2) We can check if relations are functions if there is one output for each input. Ex. input 3 - output 6       input 4 - output 6.
3) In order to model a relation or function we need to use a table and or a graph.]]> 2018-03-19 14:01:33 UTC https://padlet.com/sushakov1/xfzb3sb3lrw4/wish/243502111 https://padlet.com/sushakov1/xfzb3sb3lrw4/wish/243502134 1) A function has only one output for the given input, and a relation is a set of both inputs and outputs.
2) If each input maps to exactly one output, and the vertical line test.
3) you can graph them.]]> 2018-03-19 14:01:35 UTC https://padlet.com/sushakov1/xfzb3sb3lrw4/wish/243502134 https://padlet.com/sushakov1/xfzb3sb3lrw4/wish/243502188 1) With functions you can expect the same output everytime(like machines), but with relations you cant
2) The vertical line test
3) using tables and graphs]]> 2018-03-19 14:01:40 UTC https://padlet.com/sushakov1/xfzb3sb3lrw4/wish/243502188 https://padlet.com/sushakov1/xfzb3sb3lrw4/wish/243502399 1)Because a function works like a machine, and a relation is simply saying something like, today and yesterday, I ran a mile.  This means that this simply just showing what this person did those days, it does not have a constant pattern and does not work like a machine 
2) If you have the same input in two places and get a different output in both of them, that means it is not a function.
3) using tables/ and or graphs ]]> 2018-03-19 14:01:57 UTC https://padlet.com/sushakov1/xfzb3sb3lrw4/wish/243502399 https://padlet.com/sushakov1/xfzb3sb3lrw4/wish/243502446 1)A function always has one output for every input. 
2)If all inputs have one line connected, then the outputs are a function of the inputs
