Answer:

f^-1(3) =7

Step-by-step explanation:

no calculate f^-1 :

let : f^-1(3) =a so : f(a) = 3

(2a-2)/4 = 3

2a-2 = 12

2a=14

a = 7

f^-1(3) =7

Answer:

Step-by-step explanation:

y = (2x - 2) / 4 Interchange x and y

x = (2y - 2) / 4 Multiply both sides by 4

4x = 2y - 2 Add 2 to both sides.

4x + 2 = 2y Divide both sides by 2

4x/2 + 2/2 = 2y / 2

2x + 1 = y

Now put 3 in wherever you see an x

2*3 + 1 = y

6 + 1 = y

7 = y

Devise the exponential growth function that fits the given data, then answer the accompanying question. Be sure to identify the

NemiM [27]

Answer:

The cost in 2015 will be $283.45.

What is the reference point (t=0)?

d. The year 2005.

Step-by-step explanation:

The exponential growth model for the cost is the following:

$C(t) = C_{0}e^{rt}$

In which C(t) is the cost after t years, $C_{0}$ is the initial cost and r is the decimal inflation rate

In this problem, we have that:

$C_{0} = 190, r = 0.04$

What will it cost in 2015 assuming the rate of inflation remains constant?

2015 is 10 years after 2005, so this is C(10).

$C(t) = C_{0}e^{rt}$

$C(10) = 190*e^{0.04*10} = 283.45$

The cost in 2015 will be $283.45.

The reference point is the year in which t = 0, so the year 2005.

How do you Identify and contrast the differences between the rise in prices due to inflation and the rise in prices in microecon

andrezito [222]

One can Identify the differences between the rise in prices due to inflation and the rise in prices in microeconomic markets by?

Observing the trends in prices.
Observing Demand and supply curve.

<h3>Contrast the differences between the rise in prices due to inflation and the rise in prices in microeconomic markets.</h3>

The difference that exist between a rise in price due to the inflation and a rise in price due to microeconomic markets is based on the price changes that has occurred in terms of demand and supply model.

Note that this is said to be the price in a given market but the price rise as a result of to inflation tells that the price rise is one that reaches a lot of markets and not only just one market.

Hence, One can Identify the differences between the rise in prices due to inflation and the rise in prices in microeconomic markets by?
