hello

OpenStudy (anonymous):

yes , function table If I deserve medal then give me one.

OpenStudy (anonymous):

wait what is the rule a.y=x-10 b.y=6x c.y=6-60 x=11

OpenStudy (anonymous):

which one? this one ? x y 12 2 30 5 42 7 72 12

OpenStudy (anonymous):

sorry I don't get waht u ask?

OpenStudy (anonymous):

wats is the rule for this function table

OpenStudy (anonymous):

for this what is the rule of this function table x y 12 2 30 5 42 7 72 12 if u cross n mutiply it equation than it funtion EXample: (30*2)=(12*5) (42*5)=(30*7) (72*7)=(42*12) yes

OpenStudy (anonymous):

wats the answer

OpenStudy (anonymous):

do u want to know this table x y 12 2 30 5 42 7 72 12 let do x= 72, y=7 than set up equation (72/11)=(7/y) Cross time 72y=77 y = 77/72 funtion with this eqution a.y=x-10 b.y=6x c.y=6-60 x=11 than plug x= 11 solve for y .y=(11)-10 y=-1 -1 not equatiom to 77/72 than the table not funtion with this equation

OpenStudy (anonymous):

plug all x to find y to see if y = 77/72 than funtion if not equal to 77/72 than not funtion
