Problem 114 of 7
Write an exponential equation from graph features horizontal asymptote y=0, y-intercept 20, decay factor 0.9.
Using a hint is okay. It just tells the trainer to give you a little more review.

Your answer is equivalent to the expected form.
Walkthrough
Full solution stays hidden until you ask for it.
1. Use vertical shift as horizontal asymptote.
2. Subtract asymptote from a known point to find multiplier.
3. Use the growth or decay factor as the base.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Using the asymptote as the initial multiplier.
