# How to Graph a Table of Values

## Transcript

Hi, I'm Rachel, and today we're going to be going over how to graph a table of values. Graphing a table of values is pretty simple. We literally take the plots, take the points that we have plotted from the table of values and just literally plot them on the graph. So let's say that we have the function Y equals X squared. Well, let's look at our table of values. So we could use different points like 0, negative 1, 1, negative 2 and 2. So we have our table of values, let's make it right now, 0 squared, here I'll write the equation up here just in case you forget, Y equals X squared. So 0 squared is 0, Y equals 0. Negative 1 squared right is going to be 1. So Y equals 1, 1 squared is also going to be 1, negative 2, quantity squared is going to be 4 so that's 4 and 2 squared is also 4. So we have 4 here. So you can kind of see a trend on how this is turning out. So here is the point 0, 0, negative 1, 1, 1, 1, negative 2, 4 and 2, 4 from our table of values. Now we look at the graph. Well let's plot out the points. We have 0, 0. We have negative 1, 1, so negative 1, 1, we have 1, 1, 1, 1, negative 2, 4, go over negative 2 and up 4, 2, 4, so go over 2 and up 4 and as you can see, we've graphed a nice parabola which represents Y equals X squared. And that's how we graphed it from the table of values. I'm Rachel and thank you for learning with me today.
