Which set of functions f satisfying the given condition IS NOT a subspace of the vectorial space F(|R) of real functions with real variable. a) f(x) = -f(x), for every x ∈ |R
b) f(0) = 0
c) f(x) = k, for every x ∈ |R, with k as a non zero real constant.
d) f(-x) = f(-x), with x ∈ |R

Geometric pattern of 2 i’m guessing. not really sure about what you’re asking but i hope this !

At a constant it will take one hour to travel 32 mi.at that speed it will take 1/2 hr to travel the remaining 16 mi.it will take 1+1/2 hr to travel the 48mi @ 32mph.so 1 hr = 60 min& 1/2 hr = 30 min1+1/2 hr = 90 min.there are 60s in each 90 × 60 = 3600 seconds.the real question seriously is he why are they driving so slow? ! lol.
