Answer:
The domain is -∞ < x < ∞ ⇒ answer B
Step-by-step explanation:
* lets revise the meaning of the domain
- The domain is the values of x
- The domain is all the values of x which make the function is defined
- If there are some values of x make the function undefined, we
exclude these values from the domain
* Now lets look to the figure
- It is a straight line because its ends are arrow, that means the line
is a straight line no starting point or ending point
- That means x can be any real number
- There is no value of x make the function undefined
∴ The domain of this function is all real numbers
∴ The domain is (-∞ , ∞)
OR
∴ The domain is {x I x all real numbers}
OR
∴ The domain is -∞ < x < ∞
