The correct option regarding the domain and the range of the function f(x)= is given by that the domain is (-∞,∞) and the range of the function is (k,∞).
Given a function f(x)=.
We are told to find the domain and range of the function.
The domain is basically the values which we enters in a function.
The range is basically the values which we are getting by entering some values in the function.
An exponential function is given in the function which has no restrictions hence the domain is (-∞,∞).The range depends on the vertical shift given by k. Hence the range of function is (k,∞).
Hence the correct option regarding the domain and the range of the function f(x)= is given by that the domain is (-∞,∞) and the range of the function is (k,∞).

Answer:
71.63 kilowatts hours
Step-by-step explanation:
We are told in the question:
John's electricity bill costs $20.90 per month plus $1.23 per kilowatt hour.
We are to find, How many kilowatt hours can he use and keep his monthly cost no more than $109.
Step 1
$109 - $20.90
= $88.1
$88.1 is the amount left to spend on killowatts of electricity per hour after removing the normal monthly electricity bill in a month
Step 2
$1.23 = 1kilowatts per hour
$88.1 = y kilowatts per hour
Cross Multiply
= $1.23 × y kilowatts per hour = $88.1 × 1 kilowatts per hour
y kilowatts per hour = $88.1 × 1 kilowatts per hour/ $1.23
= 71.62601626kilowatts hour.
Approximately = 71.63 kilowatts hour
Therefore, John can use 71.63 kilowatts per hour and keep his monthly cost no more than $109

Answer:
sorry but I don't know the answer
First remove the parenthes as there is a negtive outside the second parentheses the signs of the terms inside change.
= 2n^4 - 8 - 3n - 4n^2 - 7n - 4
Now simplify like terms
= 2n^4 - 4n^2 - 10n - 12
= 2(n^4 - 2n^2 - 5n - 6)
