Answer:
<u>(3,7)</u> (7,3) (−1,14) <u>(0,1)</u> <u>(12,25)</u>
<u>(5,11)</u> (0,12) (1,8) (12,0) <u>(−1,−1)</u>
Step-by-step explanation:
We have the following function:
.
We are going to check if each ordered pair is a solution.
(3,7)
If when , it is a solution.
This ordered pair is a solution.
(7,3)
If when , it is a solution.
This ordered pair is not a solution.
(-1,14)
If when , it is a solution.
This ordered pair is not a solution.
(0,1)
If when , it is a solution.
This ordered pair is a solution.
(12,25)
If when , it is a solution.
This ordered pair is a solution.
(5,11)
If when , it is a solution.
This ordered pair is a solution.
(0,12)
If when , it is a solution.
This ordered pair is not a solution.
(1,8)
If when , it is a solution.
This ordered pair is not a solution.
(12,0)
If when , it is a solution.
This ordered pair is not a solution.
(-1,-1)
If when , it is a solution.
This ordered pair is a solution.
The answer is
first you must multiply or use the FOIL method (First, Outer, Inner, Last)
First you multiply the first terms
this gives you 3x^2, then you multiple the outer terms
this gives you -21x, then you multiply the inner terms
that gives you 2x, finally you multiply the last terms
that gives you 14, now you combine like terms
now you put all the terms together and end up with your solution
