Let f: R R and g: R R be two one-one and onto functions such that they are the mirror images of each other about the line y=2 . If h(x)=f(x)+g(x) then h(0) equals to __________.

Correct answer

4

Step-by-step solution

Since f(x) and g(x) are one-one and onto and are also the mirror images of each other with respect to the line y=2 . It clearly indicates that h(x)=f(x)+g(x) will be a constant function and will always be equal to 4 .
