Consider “m v l, (m ⊃ i) ∙ (l ⊃ i) .·. i ≡ (m ∙ l)”. in the truth table for determining the validity of this formula, which truth values go in the column under m on the left-hand side – assuming that the propositional letters are listed in the order in which they appear in the formula?
a) ttffttff b) ff c) d) tftf

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.

its very big question plz make it small
