Select the correct answer. Which statement describes the end behavior of the function?
f(x)= x squared-4/x squared-9

ОА.
The function approaches O as x approaches - and co.
OB. The function approaches 4/5 as x approaches -- and co.
OC. The function approaches 2/3 as x approaches - and co.
OD. The function approaches 1 as x approaches -co and co.

D. The function approaches 1 as x approaches and

Step-by-step explanation:

When evaluating end behavior, take the limit as the function goes to negative and positive infinity.

When evaluating limits to infinity, terms less than the highest degree are irrelevant:

Therefore, the function approaches 1 as x approaches and

lo.lll

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.
