How are the real solutions of a quadratic equation related to the graph of the quadratic function?
The real solutions are the points at which the graph of the function crosses the x-axis. If the graph never crosses the x-axis, then the solutions are imaginary.
Where the graph crosses the y-axis?
x = 0
What is intercepting graphs and tables?
Intercept for a graph are points at which the graph crosses either axis. There is no such thing as an intercept for tables.
What is the definition of y-intercept?
The place on a graph were a line crosses the y axis
What is the value of y at a point on a quadratic graph when it crosses the x axis?
zero
How are the real solutions of a quadratic equation related to the graph of the quadratic function?
The real solutions are the points at which the graph of the function crosses the x-axis. If the graph never crosses the x-axis, then the solutions are imaginary.
Where the graph crosses the y-axis?
x = 0
What is a correlation on a scatter graph in maths?
it is the line in the middle of the crosses
How do you find the zeros in an equation by looking on a graph?
They are all the points where the graph crosses (or touches) the x-axis.
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 does the discriminant tell you about the graph?
Whether the graph has 0, 1 or 2 points at which it crosses (touches) the x-axis.
What is intercepting graphs and tables?
Intercept for a graph are points at which the graph crosses either axis. There is no such thing as an intercept for tables.
What does it mean for a function when the graph of the derivative crosses the x-axis?
This means that the function has reached a local maximum or minimum. Since the graph of the derivative crosses the x-axis, then this means the derivative is zero at the point of intersection. When a derivative is equal to zero then the function has reached a "flat" spot for that instant. If the graph of the derivative crosses from positive x to negative x, then this indicates a local maximum. Likewise, if the graph of the derivative crosses from negative x to positive x then this indicates a local minimum.
What is the point where the graph of a line crosses the horizontal axis?
y-intercept
Point where the graph of a line crosses the vertical axis?
The y intercept
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 do the zeros of a polynomial function represent on a graph?
The zeros of a polynomial represent the points at which the graph crosses (or touches) the x-axis.
