*Celeste drinks at least 8 cups of water each day. So far, she drank 1.5 cups of water. She will drink the rest of her water for the day from a water bottle that holds 2 cups
of water. Which graph shows the minimum number of bottles worth of water Celeste
should drink so that she drinks at least 8 cups of water?
I need answer fast please, no links any help is appreciated
NO LINKS PLEASE I HAVE BEEN TRYING FOR TOO LONG ALREADY

3x^3-x^2+6x-9

x= 149. 24+7=31. 180-31=149

your welcome

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
