Question

Pls solve minima & saddle points. Thank you & I will give thumbs up.

**Problem Statement:** Find all the local maxima, local minima, and saddle points of the function. \[ f(x, y) = 2xy - x^2 - 6y^2 + 2x + 4 \] **Solution:** 1. **Local Maxima:** - **Option A:** - A local maximum occurs at \(\left(\frac{6}{5}, \frac{1}{5}\right)\). - The local maximum value is \(\frac{26}{5}\). - **Option B:** - There are no local maxima. (The correct option is selected as **A**, indicating there is a local maximum at the specified point.) 2. **Local Minima:** - **Option A:** - A local minimum occurs at [fill in blank]. - The local minimum value is [fill in blank]. - **Option B:** - There are no local minima. (There is no selection made, indicating further work is required to determine local minima.)
