Question

A bacteria starts with 500 cultures and grows exponentially. The number of bacteria at time t, where t is time in hours, is given by the function g (t)=500•2^2t.

The bacteria multiplies by ____________ every hour.

Answer 1

a factor of 4

Explanation:

The equation is

`500 (2) {2}^(t)`

Which can be simplified to

`500 (4) {}^(t)`

Since 4 is the base, the constant factor is 4.
