The y-intercept is a point where the graph crosses or intersects the y-axis. Learn the definition, formula, graph, facts, examples, and much more.
Analogously, an -intercept is a point where the graph of a function or relation intersects with the -axis. As such, these points satisfy y = 0 {\displaystyle y=0} . The zeros, or roots, of such a function or relation are the x {\displaystyle x} -coordinates of these x {\displaystyle x} -intercepts.
The y-intercept of a function y = f(x) is a point where its graph would meet the y-axis and is obtained by substituting x = 0. Understand the y-intercept and its formula with derivation, examples, and FAQs.
Illustrated definition of Y Intercept: The point where a line or curve crosses the y-axis of a graph. We can often find it by setting x to zero and...
Y-Intercept of a Straight Line. Where a line crosses the y-axis of a graph. Just find the value of y when x equals 0. Example: In the above diagram the line crosses the y axis at y = 1. Example: Here the line crosses the y axis at y = −2.
15 paź 2013 · The $y$-intercept of a function $f(x)$ is the point where the function intersects the $y$-axis (if in fact it does intersect the $y$-axis) and it is found by evaluating $f(0)$, i.e., finding the value of $f(x)$ when $x = 0$.
The y-intercept of a graph is the point where it crosses the y-axis, which is the vertical axis from the xy-coordinate plane. Below, we will see how to find the y-intercept of any function and why a function can have at most one y-intercept in general.
