Need help with these please, I am having a tough time understanding

( C ) Combining these calculated values of Ax with the solid line in Fig . 8. 27 of theof AX calculated in 4 ( 2 ) , classify the bonding in NaCl and in HCI as ionic , polar covalent ,( b ) Assume that a bonding is ionic when the value of AX = 2.0 .
