Assuming 
is differentiable over the interval (1, 5), by the mean value theorem we know that there is some 
such that
We're given that 
for all 
, so
that is, the minimum possible value is 8, and the maximum possible value is 12.
It says find the product, so that means multiplication
-2[7 -4 0] = [-14 8 0] solving: [-14 8 0] [-3 0 5]
[42+0+70 -24+0+40 0+0+0]
[-14 8 0] * [-3 0 5] = [112 0 -30] = [112 16 0]
[112 16 0]*[6 2 1]
[112 0 -30]* [6 2 1] = [1008 114 0] [672+224+112 96+32+16 +0]
=[1008 114 0].
I believe the answer is 24 times
hope this helps!
I believe that is 275 because percent is just out of one hundred
