Given f(x)=7x+12 and Domain={3,6,9} find Range {21,42,63}
{9,6,3}
{33,54,75}
{19,26,33}

the answer is the 3rd option

range = { 33, 54, 75 }

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.
