Question

100 points! halp...

Which point could be removed in order to make the relation a function? ((-4.3). (-5. 6), (1, 0). (-4. 5). (9, 5), (0.-7))
(-5.6)
(1.0)
(-4, 5)
(9.51
​

Answer 1

As per defination of function

Every domain has an unique range

or

• f(x)=y

Here

• f(-4)=3
• f(-4)=5

One point need to be removed to get it function

Hence the point is (-4,5)

Answer 2

it is 3rd option C. -4, 5

Explanation:

all the elements are associated with only one second element except -4

for -4 there are two second elements 3 and 5 from the ordered pairs (-4, 3) and (-4, 5)

so we can remove one of them to make R a function

since (-4, 3) is not in the options so the correct option is (-4, 5)

so c is the right one
