Answer 10

that last example was it crossing twice

Answer 11

thx u too virtus

Answer 12

it depends on the value of the discriminant (b^2-4*a*c), if the discriminant is positive there are two intercepts, one intercept i
f the discriminant is 0 and none if the discriminant is negative.

so either 0,1, or 2 times a parabole will cross
