Describe the error in graphing the function

Step-by-step explanation:

I don't know how to do any of these if you could give me another question that's possibly easier

f(4) = (4-1) = 3

f(2) = (2-1) = 1

f(-27) = (-27 -1) = -28

There isn't any error while describing the functions and everything looks fine.

If you still have problem then send the question again with the image of your book.

Step-by-step explanation:

I hope this helps ☺️❤️

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.
