Answer:
5.
Step-by-step explanation:
For finding [tex] f(-1, 3) [/tex], we have to substitute [tex] x = -1 [/tex] and [tex] y = 3 [/tex] into the function [tex] f(x, y) = 2x - y + 10 [/tex].
The calculation is as follows:
[tex] f(-1, 3) = 2(-1) - 3 + 10 = -2 - 3 + 10 = 5[/tex]
So, [tex] f(-1, 3) [/tex] equals [tex] 5 [/tex].
[tex] \rule{180pt}{3pt} [/tex]
