What is the domain of the function shown in this graph?

Domain is the set of x. Therefore, the domain starts from least x-value or from left side to the right side.

In the graph, it shows that the domain is from x = 1 to positive infinity.

Therefore the answer is x >= 1

or [1,+infinity) as interval.

a. is correct

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)
