Question 869949: Evaluate the expression for the given f(x,y)
f(2, -3) if f(x, y) = x^2+y^2
Answer by jim_thompson5910(35256)   (Show Source):
You can put this solution on YOUR website! Plug in x = 2 and y = -3. Then evaluate.
f(x, y) = x^2+y^2
f(2, y) = (2)^2+y^2 ... Plug in x = 2 (ie, wherever you see an x, replace it with 2)
f(2, -3) = (2)^2+(-3)^2 ... Plug in y = -3 (ie, wherever you see a y, replace it with -3)
f(2, -3) = 4+9
f(2, -3) = 13
