Question

Marcello is tiling his kitchen floor with 45 square tiles. The tiles come in whole number side lengths of 6 to 12

inches. The function A(s) = 45s2
, where s is the side length of the tile, represents the area that Marcello can cover
with the tiles. What is the domain of this function?

Answer 1

Domain: {6, 7, 8, 9, 10, 11, 12}

Explanation:

Domain is the set of input values.

Now, we are told that s is the side length of the tile, represents the area that Marcello can cover and that the tiles come in whole number side lengths of 6 to 12.

Thus, the possible sizes are;

(6, 7, 8, 9, 10, 11, 12)

This will also be the domain
