10 POINTS!! PLEASE HELP Identify which functions have complex roots by selecting the function names on the provided coordinate p

dusya [7]

It's the graphs that don't touch the x-axis have complex roots. Roots are the points where the parabola touches the x-axis. A,C and E all cross/touch the x-axis so they have real roots.

non-real or complex root parabolas are: B, D, F
