How to Graph y = x^2 + 2 (using a table of values)

In this video we'll draw the graph for y = x^2 + 2 .
First, we will use a table of values to plot points on the graph. Once we have two or three points, we can draw our line for the linear equation. You can choose any values of x for your table, however, 0, 1, and -1 are often best since they result in point that will fit on your graph paper. This is likely the easiest way to graph the equation y = x^2 + 1 when you are starting to learn to graph.
Note that the graph is a parabola. If we were to graph y = x^2 it would be a parabola with the vertex at the origin (0,0). For x + 2 we just move that parabola up two on the y axis.

Thanks for the help, I was so stuck on a question but this explained it!

You are most welcome!

I'm confused what if it is y=x^2-6. I keep doing it and getting the wrong answer for the y value when trying to find the point.

[@DrBs-Other-Channel]

Probably best to put values in for x and then find y. Then graph that point. Do that until you have your parabola. Or this might help "The equation y equals x squared minus 6 represents a parabola, similar to y equals x squared, but it’s shifted downward by 6 units."

How about graph for 2x^2-3

Can you provide playlist of all graph video ?

what app are you using?

Why are you choosing the numbers 2, 1, 0, -1, and -2. That’s what throws me off

[@DrBs-Other-Channel]

It doesn't really matter what you chose, the point will be on the line. But I chose those numbers because they were more likely to give me points that fit on my graph paper. Plus the math is a bit easier. But in reality, you can choose any number.

I got a straight graph cus it gave me -2 -1 0 1 2 for the x vaule

[@wbreslyn]

But what about the y values? You have to consider those as well.

[@RWDXZQ]

@@wbreslyn I got -6 -3 2 3 6 but the line still turned out straight

[@DrBs-Other-Channel]

@@RWDXZQ so if x is zero, y = 0 squared + 2, so y = 2. If x = 1, then y = 1 squared +2, so y=3. Those would be the points (0, 2) and then (1,3). And so on...

@@DrBs-Other-Channel Ik that but on the homework packet is said I have to use certain X value there just the same as his, but they’re flipped
