Best ResponseYou've already chosen the best response.0Well that is a good start already. To work out the axis of symmetry, you need to work out the maximum y value, for example. To sketch the graph  you need to know some points dw:1370231232831:dw

Best ResponseYou've already chosen the best response.0This function never crosses the x axis, therefore there would be no solutions for x.
