A rule that never crosses the x-axis is a function that is either always positive or always negative. For example, the function ( f(x) = e^x ) is always positive for all real values of ( x ) and thus never intersects the x-axis. Similarly, a constant function like ( f(x) = 5 ) also never crosses the x-axis since it maintains the same positive value.
What else can I help you with?
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 line crosses the x-axis?
On the Cartesian plane the y axis crosses the x axis at the point of origin which is at (0, 0)
What is the x intercept of 3y equals 18?
3y =18 y = 6 That is a line intercepting y axis at 6 but parallel to he x axis - there is no x intercept - it never crosses the x axis
When x equals 1 then y equals?
Y is undefined because the line x=1 never crosses the y axis.
What is the meaning of x and y intercepts?
The x-intercept is defined by where a line crosses the x-axis. The y-intercept is defined by where a line crosses the y-axis.
The point at which the line crosses the x-axis?
The point where the line crosses the x axis? Answer: the x -intercept The point where the line crosses the y axis? Answer: the y- intercept

What is the point on a coordinate plane where the line crosses over the x axis?
The point where a line crosses the x-axis is called the x-intercept.
When x equals 1 then y equals?
Y is undefined because the line x=1 never crosses the y axis.
What is the meaning of x and y intercepts?
The x-intercept is defined by where a line crosses the x-axis. The y-intercept is defined by where a line crosses the y-axis.
What is the y-intercept of the line?
The y- intercept of a line is where the line crosses the y axis. The x- intercept is where the line crosses the x axis.
The x value of the point where a graph crosses the x axis?
It is the x intercept
Where the graph crosses the y-axis?
x = 0
A line were a line crosses the x axis is called what?
The x intercept
Which line represents the equation y equals x - 6?
It crosses the y axis at (0,6) and crosses the x axis at (-6,0). It is a straight line with a positive slope.
