Math 10 – Week 13

This week in Math 10…

This week we started the second half of our semester with Relations and Functions. It was easy at first to grasp but as we got a little further it got a but more difficult.

I am going to explain and show how to find the input (x) on a graph if it gives us the output (y) in function notation.

You are going to start by looking at the graph, then look at the formula given to you, find out what you know, this will help you find what you need to find, start with your output (as that is the number you have), go across to the point across from your output number, in this case 4, once you have found the number go directly down to see what your input number is; 2, that is your input, plug it into your formula that was given, and there is your solved answer.

Here is the video part to the explanation above.
