3(picture) convergent and divergent series

Option C

Step-by-step explanation:

The sum of finite geometric sequence states the following:

Σ

In this case, , and

Therefore,

≈  

Therefore, the correct answer is the option C

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
