Answer to Question #97893 in Algebra for ALexa

Question #97893
A rational function is a function that can be written in the form
f ( x ) = g ( x ) h ( x )
where
h ( x ) ≠ 0
.
The most basic rational function is
f ( x ) = 1 x
, where
x ≠ 0
. This is called the parent rational function.

activity to explore the function
f ( x ) = 1 x
. Take a close look at the table of values as well. Use any noticings to respond to the following questions:
What seems to be happening to the graph as it gets closer to 0 from the left side?
What seems to be happening to the graph as it gets closer to 0 from the right side?
Is the graph always increasing, always decreasing, or a combination of both? Explain how you know.
Where, if anywhere, do you think the graph crosses the y-axis? Explain how you know.
Where, if anywhere, do you think the graph crosses the x-axis? Explain how you know.

the graph of the function drops if we walk on the left side. If you walk on the right side, it increases.the graph increasing, and decreasing, so a combination of both, because it is located in mirror planes. The function does not intersect the axis Ox and Oy, because y≠ 0 (1/x≠ 0), and x≠0
