Which set of numbers is included in the solution set of the compound inequality?

{–7, 5, 18, 24, 32}
{–9, 7, 15, 22, 26}
{16, 17, 22, 23, 24}
{18, 19, 20, 21, 22}

Your solutions can only be 18 and smaller and then greater than 22
18 is included because the point there is closed
22 is not included because the point there is open
Therefore, therefore, the first set {-7, 5, 18, 24, 32}
