Answer:
(a) ∫(1+x^2)dx
Step-by-step explanation:
It's about matching patterns.
The interval is [1, 4], so those are the limits of integration. This is seen in choices A and C.
The x-value, Lk, is squared and 1 is added. This is seen in choices A and B.
The only choice that matches all parts of the pattern is choice A.
