If pay(hours) is the function that describes al's monthly pay at bit labs based on his training, pay(22 hours), pay(22), and p(22) all represent what?

a. work required to get 22 hours of training
b. hours of training for $22/hour pay
c. monthly pay with 22 hours of training
d. pay earned for 22 hours worth of work

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.
