Question

Start weather the function f(x)=e^x+e^-x/2 is odd or even

Answer 1

Answer:

It is neither

Step-by-step explanation:

We say f(x) is odd if

f(-x) = - f(x) for all real values of x.

Since, e^-x can never be a negative quantity for any real value of x, it can not be a odd function.

We say f(x) is even when

f(-x) = f(x) for all real values of x.

Since e^-x is not equal to e^x for any real value except zero, it is also not an even function.
