Nechta sohada ular teng?
Let f(x)=x^3 and g(x)=x, both defined on the same domain X, where X is a non-empty subset of \-2, -1, 0, 1, 2\.
For how many choices of X are f and g equal functions?
f(x)=x^3 va g(x)=x bo‘lsin, ikkalasi ham bir xil X aniqlanish sohasida berilgan, bunda X — \-2, -1, 0, 1, 2\ ning bo‘sh bo‘lmagan qism to‘plami.
X ning nechta tanlovida f va g teng funksiyalar bo‘ladi?
