5-121.
  1. Think about the difference between a function and a sequence as you answer the questions below. Homework Help ✎

    1. A certain sequence has an explicit equation of t(n) = 5 · 2n. Is it possible for this sequence to have a term with the value of 200? If so, which term is it? If not, justify why not.

    2. Now think about a function with the equation of f(x) = 5 · 2x. Is it possible for this function to have an output of 200? If so, what input gives this output? If not, justify why not.

(200) = 5·2n

Solve the same equation as shown in part (a);

Can x ≈ 1.4427 be a possible input for a function?
