An x-intercept is a place where the graph crosses the x-axis. This graph crosses the x-axis at -2, -1, 1, and 2. The coordinates of these points are ...
- (-2, 0)
- (-1, 0)
- (1, 0)
- (2, 0)
Of these, only one is listed among your answer choices: (-1, 0).
Answer:

Step-by-step explanation:

<u>differentiating numerator wrt x :-</u>
(sinx)' = cos x
<u>differentiating denominator wrt x :- </u>
(1 + cos x)' = (cosx)' = - sinx
- Let's say the denominator was "v" and the numerator was "u"

here,
- since u is the numerator u= sinx and u = cos x
- v(denominator) = 1 + cos x; v' = - sinx


since cos²x + sin²x = 1

diving numerator and denominator by 1 + cos x
