-- If you know the general shape of a graph, and you can quickly determine the
x- and y-intercepts, that's often enough information to make a pretty accurate
sketch of the graph.
-- In particular, if the equation is a linear one, then you know the graph will be
a straight line; and then, as soon as you know the x- and y-intercepts, just draw
the line between them and you don't need anything else ... that's your graph.

Do functions always have x and y Intercepts?
the x is dependent and the y is independent and the x numbers cant repeat themself and yes they do have intercepts
What if you cant do find the x intercepts?
Then there is no x-intercept. No big deal. Lots of functions do not have x- intercepts. For example, y = x2 + 1 or y = 2x
What are the x-intercepts and Y-intercepts for the graph 3x plus 15 equals 5y?
X intercept: -5 Y intercept: +3
For which values does the cosecent functions have x intercepts?
The cosecant function, being defined as 1÷sin(x), has no x intercepts. It has y intercepts at ±∞. (infinity and -infinity)
How to find the x-intercepts when there is no y?
If there is no y, then the equation is of the form x = c where c is some constant value. And so the line intercepts the x axis at (c,0).
