Question 133467: Good day,
can I get help with the following question?
Use a table of values to graph f(x) and g(x) on the same set of axes.
f(x) = 2^3x and g(x) = 8^-x
I am having difficulty with picking the x values what x values would be suitable for this graph?

In order to graph the tow function, just do them one at a time.
The 8%5E-x is the same as +1%2F8%5Ex+. So as x increases, that function gets smaller.
f%28x%29+=+2%5E%283x%29+ will grow as x increases. To find a reasonable scale, find the values for both functions at x = 0 and x = 1
g(0) = 1
g(1) = 1/8
f(0) = 1
f(1) = 8
