CAT 1999 | Question: 90

Question

Answer the question based on the following information.
In each of the following questions, a pair of graphs F(x) and F1(x) is given. These are composed of straight-line segments, shown as solid lines, in the domain x $\in (2, -2).$
Choose the answer as

• A. if F1(x) = –F(x)
• B. if F1(x) = F(–x)
• C. if F1(x) = –F(–x)
• D. if none of the above is true

Answer 1

Here F1(x) is the mirror image of F(x) with respect to Y-axis . 

That means x is replaced with -x . 

So option B is the correct one .
