If the function is in this form:
y = mx + b
Then b is the y-intercept. For example if the function is y = 2x + 4 then the y-intercept is 4.

Can a function only have one x - intercept and one y - intercept?
Yes. A straight line for example, such as y = x.
What function has x-intercept -2 and y-intercept 4?
-6
How do you find the y intercept when you are given the coordinates 5 and 4?
Having one given point is not enough. A y-intercept is described as the point of intersection of a function or relation or line and the ordinate axis (or y-axis).Suppose a function intersects the y-axis at (0, 6), then 6 is the value of the y-intercept. Or if the line that passes through (5, 4) is parallel to x-axis, then y-intercept is 4; if it passes through the origin, then y-intercept is 0; if it is perpendicular to x-axis (or parallel to y-axis) there is not an y-intercept.
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 slope of the line represented by each function what is the y-intercept for each function?
In the slope-intercept form you use the slope of the line and the y-intercept to the origin has a y-intersect of zero, b = 0, and represents a direct variation. All functions that can be written on the form f(x) = mx + b belong to the family of linear function.
A linear function does not have a y-intercept?
it is impossible for a linear function to not have a y-intercept
Explain why a function at most one y-intercept?
explain why a function has at most one y-intercept
What is the formula for the y-intercept of a cosine function?
The Y-Intercept of the cosine function is X = 0, Y = cosine(0) = 1.
What is the relationship between the function's equation and the y-intercept?
The y-intercept is the value of the function (if it exists) when x = 0.
How do you find the y-intercept and x-intercept of y equals -1?
The function y = -1 has no x-intercept; its graph is a horizontal line with a y-intercept of -1.
What is the difference of x intercept and y intercept?
The y-intercept is the value of the function when 'x' is zero. That is, it's the point at which the graph of the function intercepts (crosses) the y-axis. The x-intercept is the value of 'x' that makes the value of the function zero. That is, it's the point at which 'y' is zero, and the graph of the function intercepts the x-axis.
Can there be a function if there is no y intercept?
Yes.
What is the y-intercept of the graph of y equals 2.5x?
Y = 2.5X ( + 0 ) So, zero is the Y intercept of this function.
Can a linear function does not have a y-intercept?
X = 3 A vertical line not having a Y intercept.
In general the y intercept of the function Fx equals a bx is the point?
in general, the y-intercept of the function f(X)= axb^x is the point__.
How do you find the y-intercept of a function?
The y-intercept is the value of a function f when x is equal to zero. So, substitute 0 for x into the equation and find the value of y.
What is the difference of x-intercept and y-intercept?
The x- and y-intercepts of a function are the points at which the graph of the function crosses respectively the x- and y-axis (ie. y=0 and x=0).
