Use function notation to describe the point(2,12.50)

There are an infinite number of different functions that could have 
(2, 12.5) as one of their points.

-- If the function is linear (a straight line), then we need two points to
determine what the function is.

-- If the function is not linear (a curved graph), then we need more than that.

With only one point, we can't even tell whether or not the function is linear.

I'm pretty sure it's b). i try drawing the functions out and b is the one that stands out or isnt a "line"

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.
