(a) Find the limit of {(1/(n^(3/2)))-(3/n)+2} and use an epsilon, N argument to show that this is indeed the correct limit.

(b) Use an epsilon, N argument to show that {1/(n^(1/2))} converges to 0.

(c) Let k be a positive integer. Use an epsilon, N argument to show that {a/(n^(1/k))} converges to 0.

(d) Show that if {Xn} converges to x, then the sequence {Xn^3} converges to x^3. This has to be an epsilon, N argument [Hint: Use the difference of powers formula].

Use the graph to find the limit L (if it exists). If the limit does not exist, explain why. (If an answer does not exist, enter DNE.) h(x) = -x/2 + x2 (a) lim x→2 h(x) L = (Select One) The limit does not exist at x = 2 because the function is not continuous at any x value. The limit does not exist at x = 2 because the function approaches different values from the left and right side...
