The rate of change of a given function is given by f'(x)=dy/dx
given that the function is:
f(x)=12+2^(-2x)
f'(x)=2*(-2)e^(-2x)
f'(x)=-4e^(-2x)
the relative rate of change will be the ratio of the derivative to the original function:
f'(x)/f(x)
=(12+2^(-2x))/(-4e^(-2x))
(x-3)(6x-2)
x*6x + x*(-2) -3*6x (-2)*(-3)
6x^{2} -2x-18x+6
6x^2-20x+6
25 plus 28 equals 53 and 512 times 53 is 27,136 so he will need 27,136 blocks for all of his students hope this helped
