If `f_1(x) and f_2(x)` are defined on domains `D_1 and D_2`,respectively, then `f_1 (x) + f_2(x)` is defined on `D_1 nn D_2`.

Answer» Correct Answer - 1
Since, domain of `f_(1)(x) and f_(2)(x) " are " D_(1) and D_(2)`.
Thus, domain of `[f_(1)(x)+f_(2)(x)]" is " D_(1) cap D_(2).`
Hence, given statement is true.
