Best ResponseYou've already chosen the best response.0The equation is x^2 which means the parabola. The only difference is that because it adds one, the whole graph shifts up by one.

Best ResponseYou've already chosen the best response.0\[y=x ^{2}+1\] means that it's a Ushaped curve because a>0. it's a positive function. at yaxis, x = 0. therefore, yintercept = (0,1). at xaxis, y = 0. \[x ^{2}+1=0\] \[x ^{2}=1\] but u cant square root a negative number.. it gives u a complex root. hence there're no real roots. so the graph does not intersect the xaxis.
