Question

Which of the following statements is not always true ?

Answer 1

Ans. C We know, when an inverse function is generated, the graph of the parent function gets reversed as a mirror image with mirror on y=x line. A, B and D are hence always true. In C, there's no such rule. Even if fourth quadrant doesn't contain a point, second may or may not. Example y =2^x doesn't have any point in fourth quadrant but its inverse y=log x,base 2 has points in second quadrant.
