You know the formula of discriminant
a b
c d
that means ad-bc
So <span>we have an equation
(-12)x3-(2f)x(-w</span>²)= 2k x 3- (-14)x(-81)
0r -36 +2fw²= 6k- 1134
And 2fw²-6k+ 1098=0
But I did not know what is variable here?
When t = 0, S = 2^0 = 1
<span>When t = 2, S = 2^2 = 4 </span>
<span>Change in size = 4 - 1 = 3 cubic mm. </span>
<span>Average rate of change = (S(2) - S(0))/(2-0) = (4-1)/2 = 1.5 cubic mm/month </span>
