Final answer:
The explicit formula Aₙ=7−3(n−1) can be written in function form as f(n) = 7 - 3(n-1).
Step-by-step explanation:
The explicit formula Aₙ=7−3(n−1) can be rewritten in function form as f(n) = 7 - 3(n-1). The function f(n) represents the value of the nth term in the sequence. To find a specific term in the sequence, substitute the desired value of n into the function and simplify.
