CPM Homework Help : PCT Problem 6-101

Copy the graphs of $y = f\left(x\right)$ and $y = g\left(x\right)$ on the same set of axes.

Use graphical addition to sketch the graph of $h\left(x\right) = f\left(x\right) + g \left(x\right)$ .
Hint (a):
Make possible tables for each graph.
Add the $y$ -values to obtain $h\left(x\right)$ .
Make a reasonable guess for the equations $f\left(x\right)$ and $g\left(x\right)$ . Use this to test your graph of $h\left(x\right)$ .
Hint (b):
$f\left(x\right)$ looks like $y = x$ .
$g(x)$ looks like $y= \frac{1}{x}$ .

2 graphs, first labeled y = f of x, is increasing line passing through the origin, second labeled g of x, is rational function, both axes are asymptotes, left curve is below & left of origin, right curve is above & right of origin.
