Write a rule for the linear function in the table. i need help

x f(x)
0 3
3 15
6 27
9 39

f(x) = 4x + 3

f(x) = –4x – 3

f(x) = x + 3

f(x) = x + 3

i'm gonna go with A. f(x) = 4x + 3

Step-by-step explanation:

i hope this is the right answer.. i can't find this answer anywhere.. i can't remember the answer from a week ago :(

step-by-step explanation:

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)
