If the discriminant is zero the graph of a quadric function will cross or touch the x axis how many times?
It will touch it once.
How many times will the graph of a quadratic function cross or touch the x axis if the discriminant is zero?
Once.
If the discriminant is zero the graph for a quadric function will cross or touch the x axis how many times?
Once and the roots are said to be equal.
How many times does 1 cross the x-axis?
y=1 does not cross the x-axis. It is a line parallel to the x-axis (and therefore can't ever cross it)
How many times will a graph with a negative discriminant touch the y-axis?
A graph of an equation in the form y = ax^2 + bx + c will cross the y-axis once - whatever its discriminant may be.
How many times will the graph of a quadratic function cross or touch the x-axis if the discriminant is positive?
It will cross the x-axis twice.
If the discriminant is negative the graph of the quadratic function will cross or touch the x-axis how many times?
It would not touch or intersect the x-axis at all.
If the discriminant is zero the graph of a quadric function will cross or touch the x axis how many times?
It will touch it once.
How many times will the graph of a quadratic function cross or touch the x axis if the discriminant is zero?
Once.
If the discriminant is zero the graph for a quadric function will cross or touch the x axis how many times?
Once and the roots are said to be equal.
How many times will the graph of f(x) = x^2 + 9 Cross the x-axis?
It doesn't cross the x-axis since the position the equation is in is 9 units above the x-axis and the graph never curves the other way so it will never touch the x-axis

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.
Given the function below what is the value of the discriminant and how many times does the graph of this function intersect or touch the x-axis?
Discriminant = 116; Graph crosses the x-axis two times
How many solution will there be if the quadratic equation does not touch or cross the x-axis?
0 real solutions. There are other solutions in the complex planes (with i, the imaginary number), but there are no real solutions.
How many times does the graph of the function below touch or cross the x-axis 4x2-7x 40?
Without knowing the plus or minus value of 40 it's difficult to say but in general:- If the discriminant of a quadratic equation = 0 then it touches the x axis at 1 point If the discriminant is greater than zero then it touches the x axis at 2 points If the discriminant is less than zero then it does not touch the x axis
