What is the range of the reciprocal function ?
melamori03 [73]

Answer:

B

Step-by-step explanation:

The range is the set of y-values for which the function is defined.

** Attached is the graph of the function

By looking at the graph, we can clearly see that there aren't any y-values that is not permitted in the graph. The function is defined for all y-values. Hence the range is set of all real numbers, or, the range is (-∞, +∞)

Answer choice B is right.

EASY MEDAL !!!!!
Aleksandr-060686 [28]
Let's start with the given polynomial:
2x² - 12xy - 32y²

As a first step, we want to regroup 2:
= 2(<span>x² - 6xy - 16y²)

Now, we want to re-write the term -6xy in order to be able to perform a partial factoring. In this case, we can write:
-6xy = -8xy + 2xy
Therefore, the polynomial becomes:
= </span>2(<span>x² - 8xy + 2xy - 16y²)

Now we factorize x within the first two terms and 2y within the last two:
</span>= 2[x(x - 8y) + 2y(x - 8y)]

We can now regroup the common term:
=2(x - 8y)(x + 2y)

Your answer is hence B = 2
