A  is a dome shaped parabola  with   vertex 5,1      so it has zeroes where it crosses the x-axis

B  this one is a bowl shaped parabola with two zeroes

C  no y = 0 values listed but if we went further to -x values we would find them

D  only dips down as low as y= 6      there are no y = 0 values.....this funtion likely has no zeroes.
