First look for the y-intercept: Set x = 0 that gives you y = ?

Then you wan´t to find the x intercepts. So set y = 0

Then 2(x-2)^2 must equal 8..

But you graph has a maximum of 8 when x = 1 seting x = 1 into the equation gives us:

Either the graph is not entierly correct or the equation is not..
