How many times will the graph of a quadratic function cross or touch the x-axis if the discriminant is zero?

It will touch it at exactly 1 point. If a quadratic function is given as f(x) = ax2 + bx + c, let the discriminant be denoted as D. Then the graph of y = f(x) will cross the x-axis at the x-values x = (-b + sqrt(D))/(2a) and x = (-b - sqrt(D))/(2a). When the discriminant D = 0, these 2 x-values are actually the same. Thus the graph will touch the x-axis only once.


If the discriminant is negative the graph of a quadratic function will cross or touch the x-axis?

No, it will be entirely above the x-axis if the coefficient of x2 > 0, or entirely below if the coeff is <0.
