What is the value of x after these statements if the starting value of x is 3.
(a) if x^2 = 5^x then x : = 25^x. (b) if x^2 > x and x^3 < 4x^2 then x : = x+ 2. (c) if 4^x < x^4 or x^5 > 5^x then x : = x^2. (d) if 5^x > 2^x xor x^2 < 11 then x : = x + 8. (e) if x > 7 then x : = x^2.

David estimated he had about 20 fish in his pond. a year later, there were about 1.5 times as many fish. the year after that, the number of fish increased by a factor of 1.5 again. the number of fish is modeled by f(x)=20(1.5)^x. create a question you could ask that could be answered only by graphing or using a logarithm.
