Indicate whether the set defines a function. If so, find the domain and range of the function.

{ (4, 8), (5, 10), (6, 12), (7, 14) }

A. A function; domain = { 8, 10, 12, 14 }; range = { 4, 5, 6, 7 }
B. A function; domain = { 4, 5, 6, 7 }; range = { 8, 10, 12, 14 }
C. A function; domain = { 4, 8, 5, 10 }; range = { 6, 12, 7, 14 }
D. Not a function

An automobile starts from rest and travels along a straight and level road. The distance in feet traveled by the automobile is given by s(t) = 10t ² , where t  is time in seconds.

Find: s(8), s(9), s(10), and s(11).

s (8) =  
s (9) =  
s (10) =  
s (11) =
