Answer:
all you have to do is select all numbers that are 0 or less
anything above 0 is wrong
Hope it Helps!
Step-by-step explanation:
Answer: Choice A
Note: the range should be
. See explanation below.
===================================================
We can plug in any real number for x to get some output for y. The domain is the set of all real numbers in which we say
which is interval notation. It represents the interval from negative infinity to positive infinity.
The range is the set of possible outputs. The smallest output possible is y = -5 which occurs at the vertex (3,-5). We can get this y value or larger. So we can describe the range as the set of y values such that
and that translates to the interval notation
.
The square bracket says "include this endpoint" while the curved parenthesis says to exclude the endpoint. Your teacher mistakenly wrote
for choice A, when they should have written 
I think either your teacher made a typo or somehow the formatting messed up. Either way, choice A is the closest to the answer.
Remember that finding terms in a geometric sequence is done by multiplying the previous term by a common ratio
. For example, we can say:


We have
. To find
, let's multiply this term by
:

Now, let's use this to find all of our other terms:



Thus, our terms are 64, 80, 100, 125, and (625/4).
Answer:
Step-by-step explanation:
That is a factorial, which is calculated by multiplying 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1 (which is a really BIG number!) 40,320 to be exact!
