The x-intercept is the point on a graph where a function or relation crosses the x-axis, meaning that at this point, the value of y is zero. It is a critical concept in understanding linear equations, quadratic equations, and various types of functions, as it provides valuable information about their behavior and characteristics. The x-intercept can be found by setting the output (y-value) of an equation to zero and solving for the input (x-value).
congrats on reading the definition of x-intercept. now let's actually learn it.
