The y-intercept is the point where the graph crosses the y-axis,
which is the line ,
or the y-coordinate of that point, since we know that the point has .
We know it is only one point, because a function has at most one value of for each value of ,
so for , there is just one value of .
In other words, the graph of a function cannot cross a vertical line (like ) more than once.

You would know if the answer is expected to be given as
or as .

The x-intercept is the point (or points) where the graph crosses the x-axis,
which is the line ,
or the x-coordinate of that point, since we know that the point has .
--> -->-->-->--> --> or .
The approximate values, are and
Again, you would know how you are expected to format the answer.
