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.
The point at which a function crosses the x-axis.
The y-intercept is the value of the function (if it exists) when x = 0.
in general, the y-intercept of the function f(X)= axb^x is the point__.
The function y = -1 has no x-intercept; its graph is a horizontal line with a y-intercept of -1.
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).
x-intercept
Yes. A straight line for example, such as y = x.
The Y-Intercept of the cosine function is X = 0, Y = cosine(0) = 1.
X = 3 A vertical line not having a Y intercept.
The y-intercept of the function ( y = \csc(x) ) occurs when ( x = 0 ). Since ( \csc(x) = \frac{1}{\sin(x)} ), and ( \sin(0) = 0 ), ( \csc(0) ) is undefined. Therefore, the function ( y = \csc(x) ) does not have a y-intercept.
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.
