In options the only even function is option A. 0 0 replyShare Please log in or register to add a comment.
3 3 votes f(x) should be positive and equal for all the values of x. only A will remain remian same if -x and +x is substituted cprdereddyy answered Jul 30, 2024 • moved May 13 by Arjun cprdereddyy comment Share Follow 0 reply Please log in or register to add a comment.

1 1 vote this graph is nothing but just the concept of even function.. a func is said even if on [f(x) ,+x] = f(x) [f(x), -x] = f(x) :. also even fucntion form symmetry over the y- axis. you can easily eliminate options by putting +x, and -x..
