Afunction, f, is defined by the set {(2,3), (4,,5)}.
if f is reflected in the line y = x,
which of the following points will be in the reflection?

{(3,2), (7,4),(5,-1)}.

Step-by-step explanation:

To find the points reflected through y=x, you are really being asked to find the inverse relation. That means we are just swapping x and y per point; like (a,b) to (b,a).

So (2,3) when reflected through y=x becomes (3,2).

(4,7) when reflected through y=x becomes (7,4).

(-1,5) when reflected through y=x becomes (5,-1).

So the inverse relation is:

{(3,2), (7,4),(5,-1)}.

answer:   n ≤ -3 or n < -5

step-by-step explanation:

-5 + 2n ≥ -11

+5             +5

2n ≥ -6

2/2 ≤ -6/2

n ≤ -3

-6 - 10n > 44

+6           +6

-10n > 50

-10/-10 50/-10

n < -5
