Question

Consider the graph of a quadratic function, y = ax2 +bx + c.

If b2 - 4ac < 0 then

Answers:

A)
the graph must never cross the x-axis.
B)
the graph must cross the x-axis two times.
C)
the graph must cross the x-axis one time.
D)
the graph must cross the x-axis three times.

Answer 1

B I think... i'm horrible with math idk

Answer 2

when \[b^2-4ac<0\] then there is no real solution
if there are real solutions (roots) the graph will cross the x axis on or two times for a quadratic equation.
but no real solutions....
