Paragraph Consider the functions, aligned f(x) & = ⁻¹ x- ⁻¹ x g(x) & = ⁻¹ x- cosec ⁻¹ x- 2 & h(x) & =m x aligned On the basis of above informations, answer the following questions. Question If the equation g(x)=h(x) has exactly 2 solutions then the range of m-
Options
- A[- , 0)
- B(0, ]
- C(- ,- ]
- D[ , )
Correct answer
A. [- , 0)
Step-by-step solution
aligned & ⁻¹ x- cosec ⁻¹ x- / 2=m x & 2 ⁻¹ x- =m x aligned for exactly two solutions the slope (m) of the line must lie in [ , 0)
