The chart represents a data set’s given values, predicted values (using a line of best fit for the data), and residual values.

A 4-column table with 4 rows. The first column is labeled x with entries 1, 2, 3, 4. The second column is labeled given with entries 6, 12, 13, 20. The third column is labeled predicted with entries 7, 11, 15, 19. The fourth column is labeled residual with entries negative 1, positive 1, g, h.
Which are the missing residual values?

g = 2 and h = –1
g = 28 and h = 39
g = –2 and h = 1
g = –28 and h = –39

g = 2 and h = –1

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.
