Question 869949
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) =  <font color="red">13</font>
