The measure of angles:
Put the value of x to the eqpressions:

Answer:
the third option
Step-by-step explanation:
took the test
The domain of the function in this case are all the values that the axis of the x takes.
We have then:
The domain is x from -4 to infinity.
Equivalently:
x: [- 4, inf)
x> = - 4
Answer:
x> = - 4
