Point b is located at

(3, 0)
(0, 3)
(0, -3)
(-3, 0)

Point B is located at (0, -3). When both x and y coordinates are positive, it lies in the first quadrant. If both are negative, it lies in the third quadrant. If x is negative and y is positive, it is in the second quadrant. If x is positive and y is negative, it is in the fourth quadrant.

step-by-step explanation:

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.
