CPM Homework Help : PC Problem 6-101

Copy the graphs of y = f(x) and y = g(x) on the same set of axes. Homework Help ✎
1. Use graphical addition to sketch the graph of h(x) = f(x) + g (x).
2. Make a reasonable guess for the equations f(x) and g(x). Use this to test your graph of h(x).

Hint (a):

Make possible tables for each graph.
Add the y-values to obtain h(x).

Hint (b):

f(x) looks like y = x.

$g(x) \text{ looks like }y= \frac{1}{x}.$
