When it asks this question, ultimately you want to plug 11 into x because its f(x). 11=-2+5.
Then you subtract 5 on both sides because of the opposite of addition is subtraction.
6=-2x
now divide on both sides
x=-3
All you have to do for each question is do (population times growth, the answer of that times 25 plus the original population and that’s 2025 population.
