Find the Domain and Range of the graph
Plz help

D: {1, 2, 3, 4, 5, 6}

R: {-1, 0, 1, 2, 3, 6}

Step-by-step explanation:

1. The domain is all the x values of the graph.

1, 2, 3, 4, 5, 6

or {1,2,3,4,5,6}

2. The range is all the y values of the graph.

3,1,-1,2,0,6

{-1, 0, 1, 2, 3, 6}

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.
