If x (0, 2 ) then the value of ⁻¹ ( 7 2 (1+ 2 x)+ ( ^2 x-48 ^2 x ) x ) is equal to
Options
- Ax- ⁻¹(7 x)
- Bx+ ⁻¹(7 x)
- Cx+ ⁻¹(6 x)
- Dx+ ⁻¹(7 x)
Correct answer
A. x- ⁻¹(7 x)
Step-by-step solution
y= ⁻¹ ( 7 2 (1+ 2 x)+ ( ^2 x-48 ^2 x ) x )= ⁻¹ ((7 x)( x)+ 1-49 ^2 x 1- ^2 x )= ⁻¹( x)- ⁻¹(7 x) [ x < 7 x]=x- ⁻¹(7 x)
