Evaluate the exponential equation for 3 positive values of x, 3 negative values of x, & at x = 0.Use resulting ordered pairs to plot a graph.State the equation of the line a symptotic to the graph:y = 3^(x-4).Any help would be appreciated.I am having the worst time with these type of problems.Thanks a bunch.

Hi jamjam,
I think we've been down this road before.
\(\displaystyle y=3^{x+4}\) is your function.
Make a table of x values that meet your requirements. Use your function to substitute these values and solve for the corresponding y values. Then plot the points.
x-values.....\(\displaystyle y=3^{x+4}\)
----------------------------------------
-3............3
-2............9
-1............27
0.............81
1.............243
2.............729
3.............2187
Horizontal asymptote is y = 0 (the x-axis).
