I pretty sure the best answer would be f(x)=cbrt(27-x)
cbrt means cube root by the way.
If there are 3 feet per yard, then all you have to do is take the 96 feet and divide by 3, this gives you 32 yards.
If you have any questions please let me know, other wise take care. (:
What you would do is you would substitute each ordered pair into their respective variables. (ie. for (0,1) you would put 0 where the x is and 1 where the y is) You would then solve the equation. If the equation is not even (ie. 2=5 would not be even but 4=4 would be), you move on to the next ordered pair.
If you follow the process right and you get the equations correct, the answer should be B. (7,-2)
