Answer:
vertical asymptote at x=-1
horizontal asymptote at y=0
Step-by-step explanation:
To find vertical asymptote we set the denominator =0 and solve for x
x+1=0 (subtract 1 from both sides)
x=-1
So, vertical asymptote at x=-1
To find horizontal asymptote we look at the degree of both numerator and denominator
there is no variable at the numerator , so degree of numerator =0
degree of denominator =1
When the degree of numerator is less than the degree of denominator
then horizontal asymptote at y=0
ANSWER
B.
EXPLANATION
The given expression is
(sin x + 1)(sin x − 1)
Note that:
This implies that,
We can factor -1 on the right hand side to get,
Note that from the Pythagorean Identity
We apply this identity to obtain:
The correct choice is B
