The function f(x) = 800(1.09)3x shows the growth due to interest that Jim earns on an investment.

The steps to calculate an equivalent function are shown below:

[Step 1] f(x) = 800(1.09)3x
[Step 2] f(x) = 800(1.093)x
[Step 3] f(x) = 800(1.09 ⋅ 3)x
[Step 4] f(x) = 800(3.27)x

Which of the following is the first incorrect step?
Step 1
Step 2
Step 3
Step 4

$$800(1.09)^{3x}?$$

anonymous · Answer

If yes, the 3 in the 3x power should be moved to make it 1.093,therefore that is the first incorrect step.
