What type of translation does 'h' have on graph written in vertex form f(x) = a (x - h)^2 + k?

(answer 2 )i’m very smart that’s how i know the answer.

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.

Ya i could just need to know what type of math
