The x-intercept is the point a line, represented by a function, where it crosses the x-axis on the graph. The x-intercept is written as (x, 0), because the y-coordinate is always zero at the x-intercept. Finding x-intercepts and y-intercepts
To determine the x-intercept, we set y equal to zero and solve for x. Similarly, to determine the y-intercept, we set x equal to zero and solve for y. ...
To find the x-intercept, set y = 0 \displaystyle y=0 y=0.
To find the y-intercept, set x = 0 \displaystyle x=0 x=0. The x-intercepts are where the graph crosses the x-axis, and the y-intercepts are where the graph crosses the y-axis. ... In the same way, the x-axis is also the line "y = 0". Then, algebraically, an x-intercept is a point on the graph where y is zero, and. Rational functions can have zero, one, or multiple x -intercepts. For any function, the x -intercepts are x -values for which the function has a value of zero: f(x)=0 f ( x ) = 0 . For rational functions, the x -intercepts exist when the numerator is equal to 0. The answer is -8. Hope this helps you my friend.
