Answer: The answer is (A) y = sinx.

Step-by-step explanation: We are given to select the correct function from the options that has a domain of all real numbers.

We know that only some function and cos function has a domain of all real numbers.

Thus, out of the given options, only the since function has a domain $(-\infty,\infty)$ and range of $[-1,1].$

The domain of the other three functions are different from some function.

Thus, the correct option is (A) y = sinx.

Given A = {x | x < 1}, B = {x | x ≥ 5}, and C = {x | x = 5}, match the following items. 1. A B Ø 2. A C {x | x ≥ 5} 3. B C {x

ivann1987 [24]

Answer:

The matching is shown below.

Step-by-step explanation:

The given sets are defined as

A = {x | x < 1}

It means all the values of x which are less than 1.

B = {x | x ≥ 5}

It means all the values of x which are greater than or equal to 5.

C = {x | x = 5}

It means all the value of x is 5.

Union of two sets contains all the elements of both sets.

Intersection of two sets contains only common elements of both sets.

The matching is shown below.

Sets Correct value

1. A ∪ B {x | x < 1 or x ≥ 5}

2. A ∪ C {x | x < 1 or x = 5}

3. B ∪ C {x | x ≥ 5}

4. A ∩ B Ø

5. B ∩ C {x | x = 5}
