Form the truth table p v q => q

See attached image for the table.

Step-by-step explanation:

The table shows all 4 possible truth values for statements p and q .

p  v  q  is true if one or both of the p, q are true.

Finally, an implication (if-then) is true in every case except when the first statement (hypothesis) is true and the second (conclusion) is false.

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
