    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
