Considering only the Principal values of inverse functions, the set A= x 0 , ⁻¹(2 x)+ ⁻¹(3 x)= 4 .
Options
- Acontains two elements.
- Bcontains more than two elements.
- Cis an empty set.
- Dis a singleton set.
Correct answer
D. is a singleton set.
Step-by-step solution
aligned & ⁻¹(2 x)+ ⁻¹(3 x)= 4 & ⁻¹ ( 2 x+3 x 1-(2 x)(3 x) )= 4 aligned array ll & 5 x 1-6 x^2 = ( 4 ) & 5 x=1-6 x^2 & 6 x^2+5 x-1=0 & 6 x^2+6 x-x-1=0 & (6 x-1)(x+1)=0 & x= 1 6 [ x 0] array set A is a singleton set.
