Final answer:
The function that defines the sequence -8, -6, -4, ... is f(n) = -10 + n.
Step-by-step explanation:
The sequence -8, -6, -4, ... can be defined by the function f(n) = -10 + n.
To find this, we can observe that each term in the sequence is 2 more than the previous term. So, we can express the nth term as -10 + n, where n represents the position of the term in the sequence.
