Ijust need the equation. . i’m willing to give 25 and brainless answer.

You did say an approximate graph. Geogabra does not import items like this or I would have had a better approximation. But this one is good enough to get you going. The line is y = -x +  1.45. This graph is done on paint and then imported as an object into desmos. I got the equation just by guessing at it. You can shift the line around by changing the y intercept. You might be able to do a little better by experimenting with the slope. But you have to reproduce this on your graph so just start with y = -x and then keep moving it around until you get something that looks like what I have.

The time spent doing homework is 16 hours. That too is just an estimation, but it is close enough for your purposes.

your answer would be 12

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.
