Determine if Set of Points is a Function

Mathematics
1 answer:
Lemur [1.5K]3 years ago
3 0

Answer:

{(-5, 7), (-4, -9), (–5, – 4), (2, -6)}

Step-by-step explanation:

In a function, no two points can have the same x-coordinates. In other words, all x-coordinates of the points must be different.

{(5, -6), (-1, - 2), (2, –9), (–8, -2)} : All x-coordinates are different: 5, -1, 2, -8. This is a function.

{(-5, 7), (-4, -9), (–5, – 4), (2, -6)} : Two x-coordinates are the same: -5, -5. This is not a function.

{(-4,2), (-2,8), (-1,6), (5,6)} : All x-coordinates are different: -4, -2, -1, 5. This is a function.

{(2,2), (-4,9), (9, -3), (-3, 2)}: All x-coordinates are different: 2, -4, 9, -3. This is a function.

Which inequalities are true? Check all that apply. Three-fifths &lt; 0 Four-sixths greater-than one-half Nine-elevenths &lt; 1 T
Kipish [7]

\frac{3}{5} < 0

\frac{8}{16} > \frac{1}{2}\\\\

<em><u>Solution:</u></em>

<em><u>We have to find the inequalities that are true</u></em>

<em><u>Option 1</u></em>

\frac{3}{5} < 0\\\\0.6 < 0

0.6 is not less than 0

Thus this inequality is not true

<em><u>Option 2</u></em>

\frac{4}{6} > \frac{1}{2}\\\\0.667 > 0.5

0.667 is greater than 0.5

Thus this inequality is true

<em><u>Option 3</u></em>

\frac{9}{11} < 1\\\\0.818 < 1

0.818 is less than 1

Thus this inequality is true

<em><u>Option 4</u></em>

\frac{8}{16} > \frac{1}{2}\\\\

0.5 = 0.5

Thus the above inequality is not true
