Hello!
We can look at each answer choice to verify whether it has a restricted domain or not:
A.
This is a function similar to a cubic root function. Its domain is (-∞, ∞), so it has no restriction.
B.
This is a square root function. This graph only consists of x-values in the interval (3, ∞) because you cannot take the square root of a negative number. This function has a restricted domain.
C.
This is a cubic function, so it has an interval of (-∞, ∞)
D.
This is a quadratic function, which has no domain restriction.
Therefore, the correct answer is B.
Answer:
It is a relation but not a function. I hope this helps :)
Step-by-step explanation:
If you do the vertical line test it will go through two points and not one so it’s not a function
