algebrathe points at which the graph intersects the xaxis.
An intercept is defined as a point where an equation crosses the axis. For example, the line graphed below crosses the axis at the point
In the case of functions that cross the axis multiple times, like a quadratic equation, there are multiple interepts.
The xintercept of a graph is the point(s) at which the graph intersects the xaxis. In other words, it is the value of x when the function or equation’s output (yvalue) is zero. For example, in a linear function given by , the xintercept is the solution to the equation , which simplifies to .
If a graph has multiple xintercepts, this indicates that the function or equation equals zero at multiple distinct xvalues. Conversely, if a graph does not intersect the xaxis, the function or equation has no real roots.
A function is a mathematical relationship between two sets, called the domain and the codomain, in which each element in the domain corresponds to exactly one element in the codomain. Functions are often represented by equations, graphs, or tables and can model realworld scenarios or abstract concepts.
A graph is a visual representation of a function or a set of data in the Cartesian coordinate system. It helps in understanding the behavior of the function or the trend in the data. The horizontal axis is usually denoted as xaxis and the vertical axis as yaxis.
