Let
x-------> the number of persons in the family
f(x)------> the function represent the cost of living
we know that
The domain of the function would only include positive integers, because the number of persons can not be negative or a fraction
The range of the function would only include positive numbers, because the cost can not be negative
therefore
<u>the answer is the option B</u>
The domain would only include positive integers.
You take 15*15 and you take 8*8 and then you add them both together
Answer:3/5
Step-by-step explanation:when he takes one marble it’s 7/11 and when he takes another it’s 6/10 so simplify and you get 3/5
Y = sqrt(x - 5) - 1
for the square root to be a real number x must be >= 5
The domain is x>= 5 , or in interval notation [5, ∞)
