denis-greek [22]

Answer:

s = -3

Subtract 9 from each side

s + 9-9 =   6-9

A city’s population, P, is modeled by the function P(x) = 78,500( 1.02 )x where x represents the number of years after the year
serg [7]
I presume this is meant to be exponential.

When f(x) = a(b)^x, a represents the starting value, b represents change, and x represents time.

The population began in 2000 (x = 0). This makes the equation equal to 78,500, which is your starting value and population in 2000.

1.02 means that the initial value is multiplied by 1.02 or 102% each year. Therefore, there is a 2% increase.
