A colony of bacteria starts with 1000 cells and grows exponentially. The number of cells after t hours is given by B(t)=1000⋅2t. How many bacterial cells will be in the colony after 4 hours?

Step-by-step explanation:

1000(2t)

1000(8)

8000 if t is equal to 4 hours

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
