We have to find the domain of the function:
f ( x ) = ln ln ln x
x > 0
ln x > 0
x > 1
and finally: ln ( ln x ) > 0
ln x > 1
x > e
Answer:
Domain is: x ∈ ( e , + ∞ ).
Answer:
I'm not sure what method this was but I added up all the numbers and divided it by 5.
Step-by-step explanation:
The answer is 13. I added up all the numbers to get 65. Then, I divided 65 by 5 to get 13. Hope this helped!
Answer:
y is 6.5 because it's kind of a ratio, you just need to find out what number to divide them by or multiply them by in this case, it was 13÷2 =6.5
Answer:
75
Step-by-step explanation:
Four scores.... add them together and divide by four
(90 + 80 + 70 + 60) / 4 = 75
Answer:
f^-1(x) = 3 - 5x, second option
Step-by-step explanation:
To determine the inverse simply interchange the variables and solve for y;
f(x) = 3 - x / 5 -> Interchange the variables
x = 3 - y/5 -> Multiply either side by 5
5x = 3 - y -> Subtract three from either side
- y = 5x - 3 -> Divide either side by - 1
y = - 5x + 3
Your solution is f^-1(x) = 3 - 5x
