Answer 2

Step-by-step explanation:

A={-24,-12,-8, -6, -4, -3, -2, -1, 1, 2, 3, 4, 6, 8, 12, 24}

Step-by-step explanation:

The given set is

A={x:x is a factor of 24}

This is the set builder form of set A because it is defined by the properties.

We need to find the roster form of set A.

In roaster form we list all the elements of that set.

Factors of 24 are ±1, ±2, ±3, ±4, ±6, ±12, ±24.

Since set A is defined as x where x is divisible by 24, therefore the raster form is

A={-24,-12,-8, -6, -4, -3, -2, -1, 1, 2, 3, 4, 6, 8, 12, 24}
