Final answer:
To rewrite the provided sequence formula in function form, it becomes f(n) = 3.5 * 2.8^(n-1), where f(n) represents the value of the sequence at the nth term.
Step-by-step explanation:
The student has provided an explicit formula for a sequence and has asked to rewrite it in function form. The given formula is an = 3.5 * 2.8(n-1). To put this into function form, we will define a function f(n) such that f(n) makes use of the variable n.
Therefore, the function form of the given explicit formula is: f(n) = 3.5 * 2.8^(n-1).
This representation is in line with the concept of a function in mathematics where an input (in this case, n) is used to determine an output based on a formula.
It's important to understand that function form and explicit formula are essentially different ways to express the same mathematical relationship.
