How do I graph y=x^2+2x+3
When I graph It i get a "W" shape, is that right?
the values I used for x are 3, 2, 1, 0,1, 2, 3

That has the form of a quadratic equation so it's graph should be a parabola.

Yea, I thooght that 1 would be 2 because for 1 it was 2 but I should always sub it in the equation
Thanks

To check to see if your graph is correct I suggest Wolfram Alpha

Yea, but in this case, the line of symmetry is not the y axis right

That is true. The line of symmetry is the vertical line x = 1

The line of symmetry is the imaginary line that divides the graph into two symmetrical parts
