The graph will cross the y-axis once but will not cross or touch the x-axis.
If the discriminant is negative, the equation has no real solution - in the graph, the parabola won't cross the x-axis.
Once.
A graph of an equation in the form y = ax^2 + bx + c will cross the y-axis once - whatever its discriminant may be.
It will touch it once.
Once and the roots are said to be equal.
If the discriminant is negative, the equation has no real solution - in the graph, the parabola won't cross the x-axis.
It would not touch or intersect the x-axis at all.
Once.
No, it will be entirely above the x-axis if the coefficient of x2 > 0, or entirely below if the coeff is <0.
It will cross the x-axis twice.
It will touch the x-axis and not cross it.
A graph of an equation in the form y = ax^2 + bx + c will cross the y-axis once - whatever its discriminant may be.
It will touch it once.
Once and the roots are said to be equal.
It will touch the x-axis once.
