Can someone please help me with this problem?

Write each sum in expanded form...
n
∑ f(Ck)∆Xk
k=1

(k is the subscript)

with the info you have given, this is the farthest we can go

$\sum_{k = 1}^nf(C_k) \Delta x_k = f(C_1) \Delta x_1 + f(C_2) \Delta x_2 + f(C_3) \Delta x_3 + \cdots + f(C_n) \Delta x_n$
