A holomorphic function is a function that is differentiable at every point on its domain. In order for it to be differentiable, it needs to satisfy the Cauchy-Riemann equation properties, such that:
f(z) = u(x,y) + iv(x,y)
ux = vy
vx = -uy
If that is so, then f'(z) = ux + ivx
Otherwise, if a function doesn't satisfy these conditions, we say that it's not holomorphic. For instance:
f(z) = z̅
Test with the following properties:
ux = vy
vx = -uy
z̅ is written as u(x,y) - iv(x,y). Take the partial derivatives of u(x,y) and v(x,y). Then:
ux = -vy
vx = -(-uy) = uy
Since the conditions don't hold, that function is not holomorphic.

A __________ function takes the exponential function's output and returns the exponential function's input.
No. The inverse of an exponential function is a logarithmic function.
Logarithmic Function
An equation where the left is the function of the right. f(x)=x+3 is function notation. The answer is a function of what x is. f(g(x))= the answer the inside function substituted in the outside function.
