    k=1/2f

    Step-by-step explanation:

    f (2) = 12 therfore making, f (x) = kx^2, to f (2) = k (2) ^2 because the 'x' in f (x) is 2.

    Step 1:

    divide both sides of the equation by 2;

    f=2k

    Step 2:

    swap the sides of the equation;

    2k=f

    Step 3:

    divide both sides by 2 once again;

    k=1/2f
