Not necessarily. Consider the series
and
. Here
.
The first series converges by the alternating series test, which says
converges if
is a decreasing sequence and converges to 0. This is the case, as
as
, and each term is decreasing. (Indeed the series converges to
.)
On the other hand, the second series is a classic example of a divergent sum.
Answer:
Step-by-step explanation:
This is not a function.
A function has to have 1 y associated with each x. This relationship has 2 except for 1 point (the vertex at 3,0).
You can write a domain and range for it.
The domain is
- infinity < x < 3
The range is
-infinity < x < + infinity.
Slope-intercept form: y = mx + b, where m is the slope and b is the y-intercept.
The graph intersects the y-axis at (0, -1), therefore I immediately know that the answer is either option B or D (they are the only ones with -1 as b).
To find slope:
(1, 2), (0, -1)
2 - (-1) / 1 - 0 --> 2 + 1 / 1 --> 3/1 = 3
