1. Start with the given function: P(x; y) = 5xy - 2y + 3x

2. Substitute \(x = -1\) and \(y = 1\) into the function:

P(-1; 1) = 5(-1)(1) - 2(1) + 3(-1)

3. Calculate each term:

5(-1)(1) = -5

-2(1) = -2

3(-1) = -3

4. Add the results:

-5 - 2 - 3 = -10

5. Thus, the value of the function at \(x = -1\) and \(y = 1\) is:

P(-1; 1) = -10
