B = `{x//x "is an integer", -3/2 < x < 9/2}`
Advertisements
Solution
B = `{x//x "is an integer", -3/2 < x < 9/2}`
= {– 1, 0, 1, 2, 3, 4}
Explanation:
The Roster form lists all the integers satisfying the given conditions, which are `-3/2 < x < 9/2`. Since only integers are included, fractional values are excluded, and the set includes –1, 0, 1, 2, 3, and 4.
