Question 7 the domain of the function y = sin x - 2 is x ≥ 2. true false question 8 the domain of the function y = cos x + 1 is all real numbers. true false question 9 what is the domain of the function y = sin x? all real numbers x > 0 x ≥ 0 x < 0 question 10 what is the range of the function y = sin x? all real numbers -1 ≤ y ≤ 1 -1 < y < 1 y ≥ -1

Q7.

The domain of the function y = sin x - 2 is x ≥ 2.

FALSE because is All Real Numbers

Q8.

The domain of the function y = cos x + 1 is All Real Numbers.

TRUE

Q9.

What's the domain of the function y = sin x?

All Real Numbers

Q10.

What is the range of the function y = sin x?

-1 ≤ y ≤ 1

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
