What is the value of y at a point on a quadratic graph when it crosses the x axis?
zero
What is the point at which a graph crosses the y-axis?
This is called the y-intercept and represents the value of the plotted function at x = 0.The place where the graph crosses the y axis is called the y intercept.
What is the place or point where a graph crosses the axis is known as?
The point where a graph crosses an axis is known as an "intercept." Specifically, the x-intercept is where the graph crosses the x-axis, while the y-intercept is where it crosses the y-axis. These points indicate the values of the variable when the other variable is zero.
What is a root in a polynomial graph?
A root is the value of the variable (usually, x) for which the polynomial is zero. Equivalently, a root is an x-value at which the graph crosses the x-axis.
What happens to the y-value of the function after the graph crosses the x-axis?
When the graph of a function crosses the x-axis, the y-value of the function changes from positive to negative or vice versa. Specifically, at the point where the graph crosses the x-axis, the y-value is zero. After crossing, if the graph continues upward, the y-value becomes positive; if it continues downward, the y-value becomes negative. This behavior indicates a change in the function's output relative to the x-axis.
What is x intercept defined as?
The point at which a function crosses the x-axis.
What is the x value of the point where a graph crosses the x-axis?
It can be casually called the x intercept, but it/they is/are the root(s) of the function represented by the graph
What does the y intercept have to do with the graph?
The y-intercept on the graph shows where the graph crosses the y-axis. The value is always the value of y at that point, because x is always equal to zero.
What are the points when a graph crosses x and y-axis?
A graph crosses the x-axis at points where the value of the function is zero, meaning the y-coordinate is zero (f(x) = 0). These points can be found by solving the equation of the function for when y = 0. The graph crosses the y-axis at the point where x is zero, which corresponds to the value of the function at that point (f(0)). Thus, the y-intercept is found by evaluating the function at x = 0.
Which mathematical term describes the x-value of a point where the graph of a polynomial crosses the x-axis?
A root or a zero of the polynomial.
Point where the graph of a line crosses the vertical axis?
The y intercept
What is the point where the graph of a line crosses the horizontal axis?
y-intercept
