Your function is: f(x)=\frac{1}{2}\cos \Big( \frac{1}{4x}\Big) -1

Domain: $(-\infty, +\infty)-\{ 0 \}$ or $R-\{ 0 \}$

Range: $[-\frac{3}{2}, -\frac{1}{2}]$

Midline: $y=-1$

If (-9, 2) is on the graph of Flx), which point must be on the graph of the
dmitriy555 [2]

Answer:

(2, - 9 )

Step-by-step explanation:

Since 2 is the output when - 9 is input to f(x)

Then reversing the procedure, that is the inverse gives an output of - 9 for an input of 2.

(- 9, 2) is a point on the graph of f(x), then

(2, - 9) is a point on the graph o the inverse function f^{-1}(x)

Answer:

#1) D.$623.52  ; #2) D.17.1 ; #3) B.II and III ; #4) C.A greater availability of ATM's may make it easier to do bank transactions. Someone may choose this availability over a higher savings interest rate; #5) B.Bank E offers you a chocolate bar for filling out an application for checking and credit at the same time; #6) D.Make purchases or get cash now, and pay back the bank in monthly payments; #7) T; #8) B.Thursday ; #9) B.$1,545.83

Step-by-step explanation:

#1) 6.2% of her gross pay would be

0.062(765) = $47.43.

1.45% of her gross pay would be

0.0145(765) = 11.09

22% of the state tax withheld would be

0.22(68) = 14.96

This means her gross pay would be

765-68-47.43-11.09-14.96 = $623.52

#2) The employee benefits in addition to his gross pay would be

33500-28600 = 4900

This makes it

4900/28600 = 0.17 = 17% of his pay.

#3) Knowing where branches or ATMs are is helpful when choosing a bank.  Additionally knowledge of personal usage habits and needs will help plan where best to bank.

#4) Having more ATMs available makes banking more convenient to some customers, which is more important to some customers than high interest rates.

#5) Having a chocolate bar offered for filling out an application for checking and credit is not a good reason to examine that given bank.

#6) You cannot "borrow" against a traditional checking account and then pay it back later.

#7) An ATM withdrawal is a POS (point of sale) transaction.

#8) At the end of the day Monday, Elizabeth has

252-114.6+150 = $287.40

At the end of Tuesday she has

287.40-79.68 = $207.72

At the end of Wednesday she has

207.72-161.39 = $46.33

At the end of Thursday she has

46.33-57.40 = -11.07

This is her first overdraft.

#9) Adding together the list of items deposited we have

13.50+942.06+75.53+670.14 = 1701.23

Taking out the cash he receives gives us

1701.23-155.40 = $1545.83
