Answer:

Option A. (1,9)

Step-by-step explanation:

we know that

A<em><u> function</u></em> is a relation from a set of inputs (independent variable) to a set of possible outputs (dependent variable) where <em><u>each input is related to exactly one output</u></em>.

so

<u><em>Verify each case</em></u>

case a) (1,9)

This point preserves the function

because, each input is related to exactly one output

For x=1, y=9

case b) (8,9)

This point not preserves the function

because, each input is not related to exactly one output

For x=8, y=9 and y=-3

case c) (-3,3)

This point not preserves the function

because, each input is not related to exactly one output

For x=-3, y=3 and y=4

case d) (-6,5)

This point not preserves the function

because, each input is not related to exactly one output

For x=-6, y=5 and y=-3
