You can
put this solution on YOUR website!2y - 1/4y = 4/6
(8/4)y - (1/4)y = 4/6
(7/4)y = 4/6
y = (4/7)(4/6) = (16/42) = (8/21)
y = (8/21) this function is a horizontal line
------------------------------------------------------------------------------
(t^3 - t^2 - 4) / (t^2 + t -2)
((t-2)(t^2+t+2))/((t+2)(t-1))
cannot be simplified futher
