Question 1 of 2
1. Question
Plot the graph with equation `y=\frac{1}{x}`.Hint
Help VideoCorrect
Well Done!
Incorrect
The standard form for a hyperbola is `y=\frac{k}{x}` or `yx=k`.Create a table for `x` and `y` values, and fill in some sample values for `x``x` `-3` `-2` `-1` `0` `1` `2` `3` `y` For each value of `x` in the table, calculate `\frac{1}{x}` and put this value in the cell below the `x`-value.When `x=\frac{1}{2}`, we find `y` by `\frac{1}{x}=\frac{1}{\frac{1}{2}}=2`.When `x=0`, we cannot find `y`, because `\frac{1}{x}` is not defined, as we cannot divide by `0`.The completed table should be as shown below.`x` `-3` `-2` `-1` `0` `1/2` `1` `2` `3` `y` `-1/3` `-1/2` `-1` `2` `1` `1/2` `1/3` Plot the points in the table on a set of coordinate axes.For example the first column tells us the point `(-3,-\frac{1}{3})` should be plotted on the graph
The hyperbola will be made up of two parts in two separate quadrants. Draw a smooth curve through the points in the two quadrants.

Nice Job!
