The inverse function of the above function is f(x) = 
You can find the inverse of any function by switching the f(x) and x terms. Once you have done that, solve for the new f(x). Finally, what you'll have remaining is the inverse function. The work is done for you below:
f(x) = 
----> Switch the x and f(x)
x = 
---> square both sides
= 2f(x) + 2 ---> subtract 2 from both sides
- 2 = 2f(x) ----> divide both sides by 2
= f(x) ----> switch the order for formatting sake.
f(x) =
Answer:
- Fernando’s response is incorrect because he inappropriately applied the Rational Root Theorem.
- Dennis’ response is incorrect. According to the Fundamental Theorem of Algebra, the polynomial p(x) cannot have six roots, or zeros, because it is only of degree 3.
- Emily’s response is correct because she correctly factored the polynomial, and correctly used the definition of zeros to reach her answer.
Step-by-step explanation:
The Rational Root Theorem offers a list of possible rational roots. Each needs to be tested to see if it is an actual rational root. Fernando and Dennis made inappropriate assumptions about what the Rational Root Theorem allowed them to conclude.
Answer:
You have them both correct. #1 is B #2 is C
Step-by-step explanation:
Answer:
3.75+7.5 = 11.25
20 dollars in total how much change.
20 - 11.25 = 8.75
$8.75 change
4 days and 14 hours.
Method I used:
1. Do 110÷24 and you should get <span>4.58333333333. Ignore the numbers after the decimal point, and write down 4 as your number of days.
2. Do 4</span>×24 (you should get 96) and subtract that from 110 (you'll get 14). The difference will be the number of hours.
Hope I helped! <3
