This is algebra 2 it’s growth & decay. i need

So firstly, remember that the a variable is the initial value. Since we start off with 6.08 billion, 6.08 billion is the a variable.

Next, since this is a growth by 1.26%, add 1 and 0.0126 (1.26% in decimal form) together to get 1.0126. 1.0126 is the b variable.

Putting it together, the function is

Since 2020 is 20 years from 2000, plug in 20 into the t variable of the prior function to solve:

In context, in 2020 the population will be 7.81 billion.

the answer to this question is in the pic
