Find the limit for these problems as x approaches positive infinity.
f(x) = (1 - 3x^3) / ( 2x^3 - 6x + 2)
f(x) = (1 - 2x^3) / (x + 1 )
If Lim x --> 3 (9 - x^2) / ( x -3)
If Lim x --> 1 ( x^2 - 4x - 5) / ( X^2 - 1)
f(x) = (1 - 3x^3) / ( 2x^3 - 6x + 2)
f(x) = (1 - 2x^3) / (x + 1 )
If Lim x --> 3 (9 - x^2) / ( x -3)
If Lim x --> 1 ( x^2 - 4x - 5) / ( X^2 - 1)
Solution
Using L\'hospital rule
a) -9x2/(6x2 -6)
= -18x/(12x)
= -3/2
b) => -6x2/1 = -
c) => -2x/1
= -6
d) (2x -4)/2x
= -1
