F(x) = f(-x) is even, and f(-x)=-f(x) is odd. to know if it's even or odd you take the function and plug in -x for x then simplify it. if it's the same function that you started with , it's even. for example
if you have this
f(x) = -3x^2+4
plug in -x for x which will turn out to be
f(-x) = -3(-x)^2+4
and when simplified it'll be
-3x^2+4 because (-x)^2 is (-x)(-x) which is a positive.
because it's the same, it's an even one.

Answer:
(<) this means less than
(>) this means greater than
So since the question doesn't say anything about -4°C we can automatically cross out A and B
They are both negative! but when you have a negative. Its going to be less than a positive
So this means 4°C is greater than -5°C
or in other words
D.) 4°C > -5°C
hope this helps!
