A.2 I did graph on my calculator finds out the function intersect both x-axis and y-axis(Hope it help:)

The discriminant, b^2 - 4ac, will tell you how many and what type of solutions you have in a quadratic equation.
a= 2 b= -3 c= 1
(-3)^2 -421
9-8=1
Since the discriminant is a positive real number, there will be two real solutions,
So the graph will cross the x axis in two places. The answer is A
