Heather is going to graph y = -3x^2 + 3. how is the parent graph transformed?

Using a graphic tool
see the graphic in the attached file  

The answer is the option A) The parent graph is reflected over the x-axis, has a vertical stretch by a factor of 3 and is shifted up 3 units

7.666270253x10 raised to the 18th power

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.
