A population of flies grows according to the function p(x) = 5(2)^x, where x is measured in weeks. A local spider has set up shop and consumes flies according to the function s(x) = 3x + 2. What is the population of flies after three weeks with the introduced spider?

i forgot to put "^" before the x in 5(2)^x. would solving it still be the same way as you wrote?
