Question 314981
<font face="Garamond" size="+2">


Real number zeros are where the graph crosses the *[tex \Large x]-axis.  If the graph does not intersect or is not tangent to the *[tex \Large x]-axis, then the roots are complex conjugates and you cannot determine them from a graph of the function mapped to *[tex \Large \mathbb{R}^2]
