Homework Statement
Let f(x) = x^2 and let P = { -5/2, -2, -3/2, -1, -1/2, 0, 1/2 }
Then the problem asks me to compute Lf (P) and Uf (P).
Lf (P) =
Uf (P) =
The Attempt at a Solution
Please explain how to solve. I thought that L[f] meant to calculate the lower bound with respect to f(x). and U[f] meant to calculate the upper bound with respect to f(x). Therefore, I plugged in 0 for f(0) = 10sin(0) = 0 for the lower bound. And π/2 for the upper bound. Therefore, f(π/2) = 10sin(π/2) = 10. However, these were both wrong.[/B]
