For a function y=f（x），the range of x is called () f（x）
A: domain of function
B: range of function
A: domain of function
B: range of function
举一反三
- The production function f (x,y) = x + y has constant returns to scale
- 以下会报错的是？ A: function a(x, y, z=10) {} B: function a(x, y, z=9+1) {} C: function a(x, x, z=11) {} D: function a(x, y, z+1) {}
- 5. Known mathematical function V = f (x, y, z), you can call the function vol_visual4d (x, y, z, V) to set the slice. ( )
- 阅读下面的JavaScript代码 function f(y) { var x = y * y; return x; } for(var x = 0; x < 5; x ++) { y = f(x); document.writeln(y); } 输出结果是
- 阅读下面的JavaScript代码,输出结果是 function f(y) { var x=y*y; return x; } for(x=0;x< 5;x++) { y=f(x); document.writeln(y); } "
