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.
What else can I help you with?
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
Can the graph of a polynomial function have no y-intercept?
No, the graph of a polynomial function cannot have no y-intercept. A polynomial function is defined for all real numbers, and when you evaluate it at (x = 0), you get the y-intercept, which is the value of the function at that point. Thus, every polynomial function will intersect the y-axis at least once, ensuring it has a 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.
Is the y intercept the same as a absolute value parent function?
No, the y-intercept is not the same as the absolute value parent function. The absolute value parent function, represented as ( f(x) = |x| ), has a vertex at the origin (0, 0), which serves as its y-intercept. While the absolute value function does have a specific y-intercept, the term "y-intercept" generally refers to the point where any function crosses the y-axis, which can vary depending on the function in question.
Which form of a quadratic function tells you the y - intercept of the function?
The y-intercept of a quadratic function can be easily identified in the standard form, (y = ax^2 + bx + c), where (c) represents the y-intercept. When (x = 0), the function simplifies to (y = c), directly giving the y-intercept. In contrast, the vertex form (y = a(x - h)^2 + k) does not explicitly show the y-intercept without further calculation.
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.
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 there be a function if there is no y intercept?
Yes.
Can a linear function does not have a y-intercept?
X = 3 A vertical line not having a Y intercept.
