Answer:
We now want to find the best approximation to a given function. This fundamental problem in Approximation Theory can be stated in very general terms. Let V be a Normed Linear Space and W a finite-dimensional subspace of V , then for a given v ∈ V , find w∗∈ W such that kv −w∗k ≤ kv −wk, for all w ∈ W.

Answer:
The answer is C.
Step-by-step explanation:
When you add the same negative and positive number it's 0.
For Example:
-5 + 5= 0
Answer:
36/-4
Step-by-step explanation:
