Is the following relation a function?<br><br> {(3, −2), (1, 2), (−1, −4), (−1, 2)}

mel-nik [20]

Answer:

<h2>It's not a function.</h2>

Step-by-step explanation:

A function is a process or a relation that associates each element x of a set X, to a single element y of another set Y.

We have:

{(3, -2), (1, 2), (-1, -4), (-1, 2)}

for x = -1 are two values of y = -4 and y = 2. Therefore this realtion is not a function.

Four bread rolls weigh a total of 3/5 pounds. How much does each bread roll weigh?

timama [110]

Well, for his you would have to find the unit rate.
The easiest way to do this would first be converting 3/5 into a fraction (0.6)

next, divide that by 4 to get the weight of 1.

0.6/4 (the same as 0.6 x 0.25 or 6/10 x 1/4 if you are doing it without a calculator)

each bread weighs 3/20 (or 0.15) pounds.
