Consider the following function. f(x) = 5x 6 - X if x 1 if 1 < x 7 if x > 7 Find the following values. f(1) f(7) lim f(x) x-1- = = lim f(x) x+1+ lim f(x) x-7- lim f(x) x7+ = = = Find each x-value at which f is discontinuous, and for each x-value, determine whether f is continuous from the right, or from the left, or neither. x =
