Question

If A = $\{x:xisaninteger,\frac{-3}{2}<x<\frac{11}{2}\}$,then A written in Roster form is

• A. A = {-3,-2,-1, 0, 1, 2, 3, 4, 5}
• B. A = {-1, 0, 1, 2, 3, 4, 5,6}
• C. A = {-1, 0, 1, 2, 3, 4, 5}
• D. A = {-2,-1, 0, 1, 2, 3, 4, 5}

Answer 1

The correct option is C

A = {-1, 0, 1, 2, 3, 4, 5}

$\frac{-3}{2}=-1.5$

$\frac{11}{2}=5.5$

All integers between -1.5 and 5.5 are {-1, 0, 1, 2, 3, 4, 5}

A = {-1, 0, 1, 2, 3, 4, 5}
