What do you need help with?
Answer: 5 and 15
Step-by-step explanation:
To find what 25 percent of 130 is we must convert 25 to a decimal. 0.25
Then we multiply .25 and 130 to get 32.5 dollars off 130. This means that the radio and earphones will cost $97.50 and you will have $2.50 remaining.

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.
