Question 251614: 1. the exponential equation for three positive values of x, three negative values of x, and at x=0. Show your work. Use the resulting ordered pairs to plot the graph; State the equation of the line asymptotic to the graph (if any).
y = 5x - 3
2. Solve the problem.
Yearly sales of an electronic device S(t), in millions of dollars, t years after 1998 can be estimated by
S(t) = 100 ∙ 6t .
What is the doubling time for the yearly sales?

I think you wrote the problem down wrong. As this is in the logarithm section and the formula is most likely exponential. I think the problem should be:
f(t)=100e^rt OR f(t)=100*6^t
I don't think you can find the "doubling time" your originally written equation because t(0) (the sales in 1998) is 0.
