As we know, the expression:
x (x tends to infinity)
it means that x assumes values greater than any real number and x (x tends to less infinity) likewise indicates that x assumes values smaller than any real number.
The) , that is, as x increase, y tends to zero and the limit is zero.
B) , that is, as x decreases, y tends to zero and the limit is zero.
ç) , ie when x approaches zero by the right of zero or by values greater than zero, y tends to infinity and the limit is infinity.
d) , ie when x tends to zero on the left or by values less than zero, y tends to less infinity
Limit of a polynomial function to
Let the polynomial function . So:
Similarly, for we have:
