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.

Can you provide playlist of all graph video ?

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.

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

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