Answer:
- At 1pm, the number of bacteria in the dish is 1,000,000
- At 12pm, the number of bacteria in the dish is 500,000
Step-by-step explanation:
Given the information on the table

We are to follow the pattern to determine how many million bacteria were in the dish at 1 p.m. and 12 p.m.
Now:

It therefore means that the bacteria population doubles every hour. Following this pattern and reducing the exponents by 1 backwards, we have:

Therefore:
- At 1pm, the number of bacteria in the dish is 1,000,000
- At 12pm, the number of bacteria is 0.5 million=0.5 X 1,000,000=500,000
F(x) = 2x - 6
y = 2x - 6
2x - 6 = y |add 6 to both sides
2x = y + 6 |divide both sides by 2
x = 1/2y + 3
f^{-1}(x) = 1/2x + 3
f^{-1}(2) = 1/2 · 2 + 3 = 1 + 3 = 4
