Write a rule for the function:

x -2, -1, 0, 1, 2
y 1/3, 1, 3, 9, 27

y = 3^(x + 1).

Step-by-step explanation:

Here the y values are increasing by a factor 3  and when x = 0 y = 3,

so  y =  (3)^1 when x = 0  - that is y = (3)^(0 + 1)  = 3.

So y = 3^(x + 1)  is the rule.

Check: when x = -2,  y = 3^(-2+1) = 3 ^-1 = 1/3.

When x = 1, y = 3(1+1) = 3^2 = 9.

connie < felicia < stew

step-by-step explanation:

stew:

we need to find the slope

m = (y2-y1)/ (x2-x1)

    = (2650-795)/(10-3)

    = 1855/7

connie:

we need to find the slope

m = (y2-y1)/ (x2-x1)

we have two points (0,0) and (4,800)

m = (800-0)/(4-0)

  m = 800/4

answer: 7 x 2/5 = 2.8 hours, is your answer. your welcome! : 3

step-by-step explanation: first work out how long it took to hose 1/7 of the lawn which is 2/5 hours. times that by 7 to get the whole lawn.

sorry i don't know the other answer. i didn't learn what a proportional relationship is.
