The population of a certain city grows exponentially. when the city was founded, it only had 1000 residents. after 1 year the city had 1050 residents. write an equation that models the population y of the city after x years.

Our function is something like

When the city was founded, 0 years have passed. So, we want

So, we can update our function: now we know that it will be something like

Similarly, we have to impose . Since

we have to impose

So, our function is

56
