Answer:
<u>Part 1:</u> Find (f/g)(4) = 3
<u>Part 2:</u> Find (f+g)(4) = 28
Step-by-step explanation:
<u>Part 1:</u> Find (f/g)(4):
(f/g)(4) means <em>divide f function by g function and simplify it. Then plug in 4 into x of that simplified function.</em>
Let's do this:
Plugging in 4 into x gives us:
The answer is 3

<u>Part 2:</u> Find (f+g)(4):
(f+g)(4) <em>means add f function and g function and simplify it. Then plug in 4 into x of that simplified function.</em>
Let's do this:
Plugging in 4 into x gives us:
The answer is 28
