Answer:
Domain: [-6, 3, -4, 1]
Range: [3, -9, 1, -4]
Explanation:
if a particular relation is written as
the x is the input value and y is the output value.
The domain is defined as all possible input values a relation can take.
The range is defined as all possible output values a relation can take.
Now in our case, the relation we have is {(-6,3), (3,-9), (-4,1), (1,-4)}. Therefore, the all possible domain values we have are [-6, 3, -4, 1].
All output values that our relation can take are 3, -9, 1, and -4. Therefore, the range is [3, -9, 1, -4].
Hence, to summerise,
Domain: [-6, 3, -4, 1]
Range: [3, -9, 1, -4]
Domain is x so I believe it would be a

Answer:
The expression x² + 8x + 7 can be factored out as (x + 7)(x + 1).
Step-by-step explanation:
You can see how this factors by looking at the last term, and the coefficient of the second term. You need to find two numbers that multiply to make seven, and add to make eight.
Because seven is a prime number, this becomes very easy. If this works at all, the numbers must be seven and one.
And lo, if you check, seven and one do indeed add up to be eight, so that's what we need to use. Let's do it:
x² + 8x + 7
= x² + x + 7x + 7
= x(x + 1) + 7(x + 1)
= (x + 7)(x + 1)
