Question

The function f(x) = 800(1.09)4x shows the growth due to interest that Jim earns on an investment.

The steps to calculate an equivalent function are shown below:



f(x) = 800(1.09)4x [Step 1]
f(x) = 800(1.094)x [Step 2]
f(x) = 800(1.4116)x [Step 3]
f(x) = (1129.27)x [Step 4]


Which of the following is the first incorrect step?
