So, there is x ≠ y with g ( x) = g ( y); thus g ( x) = 1 − x 2 is not 1-1. Of …

How do I detect whether a variable is a function?

WebTo start, note you can write f ( x, y) = 1 2 log ( x 2 + y 2), so ∂ f ∂ x = 1 2 2 x x 2 + y 2 = x x 2 + y 2 and then ∂ 2 f ∂ x 2 = ∂ ∂ x ( ∂ f ∂ x) = ( x 2 + y 2) ⋅ 1 − ( x) ⋅ 2 x ( x 2 + y 2) 2 = − x 2 + y 2 ( x 2 + y 2) 2 Can you proceed from here?
