Which relation describes a function?

Kisachek [45]

Answer:

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

Step-by-step explanation:

A function is a set of ordered pairs in which <u>no two pairs have the same first number</u>.

In other words, an <em>x</em> cannot be paired with two <em>y</em>'s.

A function takes an <em>x</em> and pairs it with one and only one <em>y</em>.

{(0,0), (0, 2), (2.0), (2, 2)} is not a function because it pairs 0 with both 0 and 2.

{(2,-1), (2, 1), (3,-1), (3, 1)} is not a function because it pairs 2 with both -1 and 1.

{(2, 2), (2, 3), (3, 2), (3, 3)} is not a function because it pairs 2 with both 2 and 3.

Answer:

$\displaystyle \sf h( - 1) = - \frac{ 2}{3}$

Step-by-step explanation:

we are given a function

$\displaystyle \sf h(x) = \frac{2x - 6}{4 {x}^{2} + 8}$

we would like to simplify it for h(-1)

in order to do so

substitute the value of x

$\displaystyle \sf h( - 1) = \frac{2 \cdot - 1- 6}{4 { (- 1)}^{2} + 8}$

by order of PEMDAS

simplify square:

$\displaystyle \sf h( - 1) = \frac{2 \cdot - 1- 6}{4 { ( 1)}^{} + 8}$

simplify multiplication:

$\displaystyle \sf h( - 1) = \frac{ - 2 - 6}{4 { }^{} + 8}$

simplify addition:

$\displaystyle \sf h( - 1) = \frac{ - 2 - 6}{12}$

simplify subtraction:

$\displaystyle \sf h( - 1) = \frac{ - 8}{12}$

reduce fraction:

$\displaystyle \sf h( - 1) = - \frac{ 2}{3}$
