A) {1, 2, 3}
B) {1, 2, 3, 4, 5, 6}
C) {1, 2, 3, 4}
D) {1, 2, 3, 4, 5}
Correct Answer: A
Solution :
The given function \[f(x){{=}^{7-x}}{{P}_{x-3}}\] would be defined, if (i) (ii) \[x-x\ge 0\Rightarrow x\ge 3\] (iii)\[(x-3)\,\le (7-x)\] Hence, range of Range of. NOTE Ifthen in A the set of elements of B which have pro-image is known as range ofwhile set B is known as codomain of.You need to login to perform this action.
