Which point on the number line shows the graph of

Hence, the point on the graph that shows the graph  of -√9 is:

                              Point K.

The points are located as:

Point J            -5.5  

Point K            -3

Point L             -1

Point M             1

Point N            4.5

Point P              7          

Point Q            10    

We are asked to find which point is located at -√9

We know that:

√9=3

Hence, -√9= -3

Hence, the point which is located at -√9 is:

                  Point K.

answer:

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.
