The table shows data collected to represent the functional relationship between the number of people attending a wedding and the cost of the wedding. What is the domain of the function represented by the table?
All real numbers
x≥0
All integers greater than or equal to zero
{5, 10, 15, 20, 25}

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)

.95

answer: (3,11) is your answer.

10 - 8 = -2

  8 - 6 = -2

etc, so -2 is the common difference
