1. ## Help: Definition of function

Greetings.

For a function, f(x), defined as follows:

1 if |x| < (1/2)
0 otherwise

how will the function f(-x) be defined?

Would greatly appreciate assistance.

Best regards,

2. For a function, f(x), defined as follows:

1 if |x| < (1/2)
0 otherwise

how will the function f(-x) be defined?

1 if -.5 < -x < .5
0 otherwise

Seems like the only plausible answer to me.

Appreciate the prompt response, Isimbot.

f(x) = f(-x)

Is this true for all functions?

since |x| = |-x| , the function will be the same.
