Yes because no same x-valu resulted in different y-values.
Answer:
we need more information
Step-by-step explanation:
To factor the given function, find a term that is divisible by both terms. For this problem, the factor would be 2, since 2x^2 and -18 are both divisible by 2.
2(x^2 - 9)
You could further factor out x^2 - 9 because it is factorable by (x - 3) and (x + 3). Thus, it would be
2(x -3)(x+3)
Answer:

Step-by-step explanation:
k is a positive integer.
Consider an arithmetic sequence:

First, find n:

Now, find the sum of these 2k+1 terms:
