Answer 1

y = 460(3^x) or f(x) = 460(3^x)

Explanation:

If you take a closer look at the number of bacteria, you'll see it multiplies by 3

Time (hrs) Number of bacteria

0 460

1 1380 or 460 x 3

2 4140 or 1380 x 3 or 460 x 3 x 3 or 460 x 3^2

3 12420 or 4140 x 3 or 460 x 3^3

so the number of bacteria is y while the time is x

then y = 460(3^x)

or f(x) = 460(3^x)

If you substitute x with the time, you'll have the number of bacteria
