How to get sum of 8 terms of a linear sequence whose first term is 6 and last 48

(1)/(3)x+(5)/(8)≥(1)/(2)x-(5)/(24)

state the largest domain of each functions f:x=1/1-x and g:x=x-1/x

state the largest domain of each functions f:x=1/1-x and g:x=x-1/x where x is the real number

state the largest domain of each functions f:x=1/1-x and g:x=x-1/x find the composite funcions fog, gof^-1 where fog means g followed by f and f^-1 denotes the inverse function of f

a)state the largest domain of each functions f:x=1/x^2-1 and g:x=x/x+2 where x is a real number b)find: i)the inverse function of g^-1 of g ii)the composite function g^-1(f(x)).In each case state largest domain

Show that the sum of n terms of the progression: logx, logx^2, log^3, logx^4...is n(n+1/2)
