We want to draw a contour map of the function f of x y is equal to y over x with an appropriate contour interval showing at least six level curves so i went ahead and already graphed what these contour lines will look like for at least the steps i chose and we can talk about how we got that once we figure out what our contour lines should look like so remember we're first going to replace f of xy with c, and we're going to then just solve for x.
00:35
So one thing that we need to keep in mind is that x cannot be equal to zero.
00:42
So as x gets closer and closer to zero, z should go towards infinity.
00:48
So we'll have this like singularity at x is equal to zero.
00:52
So that's why on the graph here i have that open circle, to kind of demonstrate that.
01:00
Now, we just go ahead and multiply over by x, and then doing that would give us y is equal to cx.
01:16
So this is just a line with slope of c, and because of that, i went ahead and chose m to be one half.
01:30
And i chose one half just due to the fact that the larger c is, the more these lines just start to cramp together...
