Mastering Algebra: How To Find The X-Intercept Of A Function

x-intercept

the x-coordinate of a point where a graph crosses the x-axis

An x-intercept is a point on the graph of a function where the graph intersects the x-axis. In other words, it is the point at which the value of y is zero. To find the x-intercept of a function, we set y equal to zero and solve for x using algebraic techniques. The resulting value(s) of x will give the x-coordinate(s) of the x-intercept(s) on the graph of the function.

For example, consider the function y = 2x – 4. To find the x-intercept, we set y equal to zero and solve for x:

0 = 2x – 4

Adding 4 to both sides, we get:

4 = 2x

Dividing both sides by 2, we obtain:

x = 2

Therefore, the x-intercept of the function y = 2x – 4 is (2, 0), which is the point where the graph of the function crosses the x-axis.
