Answer: B, D, and E

<u>Step-by-step explanation:</u>

f(x) = x² - 1

(0, 1): 1 = (0)² - 1 ⇒ 1 = -1 FALSE

(1, 0): 0 = (1)² - 1 ⇒ 0 = 0 TRUE

(3, 5): 5 = (3)² - 1 ⇒ 5 = 8 FALSE

(5, 24): 24 = (5)² - 1 ⇒ 24 = 24 TRUE

(-2, 3): 3 = (-2)² - 1 ⇒ 3 = 3 TRUE

(-4, -17): -17 = (-4)² - 1 ⇒ -17 = 15 FALSE

Which of the following graphs represents a function?

kirza4 [7]

The third graph represents a function.

In a function, every input (x value) has <em>exactly</em> one output (y value). If even a single input has zero or two outputs, the graph does not represent a function.

A good way of testing this is using a vertical line. As you move a vertical line from left to right across a graph, it should always be touching exactly one point on the graphed line.

In this case, every graph fails this vertical line test except for the third graph, so the third graph represents a function.

jimmy is moving to a new apartment. he fills a box with 4 books, 5 DVDs, and 2 CD's. when he starts unpacking his new place he p

pav-90 [236]

Answer:

$\frac{2}{11}$

Step-by-step explanation:

First, find the probability of him pulling out a book.

There are 11 objects in total, and there are 4 books.

So, the probability of pulling out a book is $\frac{4}{11}$

Next, find the probability of him pulling out a DVD after.

Since a book was taken out, there are only 10 objects left. There are 5 DVDs.

So, the probability of pulling out a DVD is $\frac{5}{10}$ , or simplified to $\frac{1}{2}$

To find the probability that this happens in order, multiply the probabilities:

$\frac{4}{11}$ x $\frac{1}{2}$

= $\frac{2}{11}$

So, the probability is $\frac{2}{11}$

What is the degree of the power function represented in the table

DiKsa [7]

Answer:

2

Step-by-step explanation:

We need to plot the points in a graph and see the general shape of the curve.

<em>Attached is the graph.</em>

<em />

This Upside Down "U" shaped curve is that of a parabola, which has the general form

$ax^2 + bx + c$

Thus, we see, the function is a 2nd degree function, highest power is 2.
