Question

Please help! and explain why

Answer 1

it is the 4th one! you can figure this out because there is an empty circle on -3 for the domain, so it must be the 4th.

Answer 2

Domain(-3 , 1]

Range [-4,0)

Explanation:

Domain is the values that x can take

x > -3 since it is an open circle and x≤ 1

Using interval notation

(-3 , 1]

The range is the value that y can take

y ≥-4 for the closed circle and y <0 since it doesn't touch 0 at x=0

Using interval notation

[-4,0)
