Answer:
(3) y = (x -3)²
Step-by-step explanation:
Try the first value of x in each function:
(1) y = 3² -3 ≠ 0
(2) y = (3 +3)² ≠ 0
(3) y = (3 -3)² = 0 . . . . . . matches the table value for f(3)
(4) y = 3² +3 ≠ 0

The only viable choice is (3).
Given that the metal strip is being installed around a bench that 6ft long 2ft wide. The metal required will be given by:
P=4(L+W)
=4(6+2)
=4(8)
=32 ft
Therefore we conclude that we need a metal strip that is 32ft long
The domain is the set of possible inputs, i.e. the x-coordinates of the points.
Here those are 6, 1 and - 3 which in order is -3, 1, 6.
Then the answer is {-3, 1, 6}.
By the way note that this relation is not a function. Do you know why?
Because the image of -3 is not stated unambiguosly.
The volume of the cube is (8 x 8 x 8) = 8³ = <em>512 cubic inches</em> (exact)
