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.

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1

answer: 12   they all have at least 28 days
