If f(x)= x-1 x-4 defines a function of R , then what is its domain?
Options
- A(- , 4) (4, )
- B[4, ]
- C(1,4) (4, )
- D[1,4) (4, )
Correct answer
D. [1,4) (4, )
Step-by-step solution
array ll & f(x)= x-1 x-4 & f(x) is defined for (x-1) 0 x 1 and x-4 0 & x 4 & Domain of f(x)=1 x - 4 or, & x=[1,4) (4, ) . array
