7) the recursive formula for a function is given as: f(0) = 3,f(x) = f(x - 1) + 8

a) geometric or arithmetic? explain how you know.

b) linear or exponential? explain how you know

a) Arithmetic

b) Linear.

Step-by-step explanation:

The recursive formula for a function is given as:

Find first terms in this sequence:

As you can see, each next term differs from the previous term by 8 (is 8 greater than the previous)m so this recursive formula represents arithmetic sequence.

Each arithmetic sequence is always linear.
