Question

The growth of a bacteria each hour is given by the function

f(x) = 250(1.07)

Which number below is closest to the number of bacteria at the end of the
second hour?

250

268

286

500​

Answer 1

I believe the answer is 286 since the equation is 250(1.07) t

this tells me that 250= original size and 1.07= growth of the bacteria and t for time or hour in this case

250x(1.07) 2

267.5x(1.07)

286.225 = 286

Answer 2

500 I guess it’s not right
