Step-by-step explanation:
The domain tells us the possible x values in a function.
Look at the function, it has a open circle at x=-4 and it has a closed circle at x=6. This means that we can any value of number that is between negative 4 and 6. It cannot be negative 4 since it has a open circle so our domain is
The range is possible y values. Looking at the function, the lowest y value is at y=-3 and it has a open circle,
the highest y value is 3 and it at a closed circle.
This means we can have any y value from -3 and 3 but not -3 since it at a open circle so our range is

Answer and Step-by-step explanation:
The sides we have are 7, , and
.
The square root of 80 is less than 9 but greater than 8 (because is 64,
is 81, and 80 is in between those two values), and the square root of 31 is definitely less than the square root of 80.
So, is the longest side.
1) The square of is:
2) The sum of the squares of the two shorter sides is:
3) Since the square of the longest side is equal to the sum of the squares of the two shorter sides, by the Pythagorean Theorem, the triangle is a right triangles.
