x - intercept(s):
set
..........since denominator cannot be zero, use numerator only
=>
x - intercept is at (,)

y - intercept:
set


y - intercept is at (,)

Vertical Asymptote(s):
.......set denominator equal to zero
=>=> and

Horizontal Asymptote(s):

Degree of numerator is less than degree of denominator: horizontal asymptote at .

Domain:
{ element : and }
or


range:


Rewrite the above equation for x in standard form and solve using quadratic formulae



-> a=y, b=1, c=-(4y+5)
Find the discriminant to the above equation

.............=
.............=
Using the quadratic formulas, the above equation gives the solutions

The solutions are real if and ≠.
Hence we need to solve the inequality
and solution will be



End-Behavior:
function end-behavior of :
as , , and
as ,

Intervals of Increasing/Decreasing:
If ' then is increasing
If ' then is decreasing
...derivate
'
Increasing , and ,
Decreasing:

Intervals of Positive/Negative:
positive when U
negative when
