Use discriminant, D = b² - 4ac
(A) D < 0 for positive values. These mean the curve does not cut through the x-axis

(B) use D > 0, for 2 distinct points, after equating the two equations.

There are no workings in my comment. Just advising you on how to approach the question, by using the discriminant.

Np. Drawing the graph is not required by the question you posted... just wait for someone to write out the solution, for you.
