Let X, Y be topological spaces, f, g : X → Y functions from X to Y , U ⊂ X an open set, and x ∈ U. Assume that f|U = g|U . Show that f is continuous at x if and only if g is continuous at x.

(1/x + 1)^2 + 6 (1/x + 1) +5

3cm and 6 and 9 cm that a possibility of that question

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.

Could you make it more clear?
