Answer:
a) = 8
Step-by-step explanation:
You add up all the numbers then divide that number by how many numbers you had. 4+5+7+11+13=40 40/5.
Do you want the rest?
The value of f(5) is -37
<em><u>Solution:</u></em>
<em><u>Given function is:</u></em>

We have to find the value of f(5)
To find the value of f(5), we have to substitute x is equal to 5 in given function
Plug in x = 5 in f(x)

Thus value of f(5) is -37
I would probably just do 91 times 60 since 60 min is 1 hour
So if he has 5 time more than he has read(5) than 5 multiplied by 5 is 25. I hope this helps
