Interpret the y-intercept of this function in the context of the situation. Use complete sentences. Jennifer is painting an office complex. One wing has a large reception area with several equal-sized offices. Before
painting, she must put tape on the baseboards. The amount of tape needed is given by the equation y = 12% + 25,
where y is total number of meters of tape, and x is the number of offices.

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.
