MCQ practice · SSC Higher Mathematics Board questions · Chapter 9: Exponential and Logarithmic Function
The function f(x) = ln(x − 2)- Which of the following is correct?
- i. is a logarithmic function
- ii. is defined for x > 2
- iii. has range R_f = (0, ∞)
Think it through first, then pick an option.
- a i and ii
- b i and iii
- c ii and iii
- d i, ii and iii
Answer and explanation
Correct answer: a i and ii
i and ii are true and iii is false: the range is R, not (0, ∞). This option is right.
Why the other options are wrong
- b i and iii: iii is false: the range of ln(x − 2) is R; so i and iii together are not right.
- c ii and iii: iii is false (the range is R); so ii and iii together are not right.
- d i, ii and iii: iii is false: the range is (−∞, ∞); the three are not all true.
