If f (x) = kx^2, and f (2) = 12, then k equals

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
