To find F(4), you simply plug 4 in for x. That means multiplying 5 by 1/2x to the 4th power. That comes out to .3125, or D. (5/16)
By the chain rule,

so

It's kinda hard to tell which values are which in the table, but if I had to guess, you should get
Answer:
18+17=35
Step-by-step explanation:
Answer:
The answer is 1
Step-by-step explanation:
Formula for finding the slope: 
Take y2 and y1 from (4,<u>4</u>) (1,<u>1</u>)
Take x2 and x1 from (<u>4</u>,4) (<u>1</u>,1)

This is how the answer is 1
Hope it helps :)
PART A: the function is
Y=25x+80
X represents the number of months.
PART B:
You plug in 6 for X
(25*6)+80=230
