Answer:
(d) f(x) = 2x^2 - 16x + 35
Step-by-step explanation:
The x-coordinate of the extreme will be found at ...
x = -b/(2a)
where the function is f(x) = ax²+bx+c.
The extreme will be a minimum when a > 0. (eliminates choices A and B)
The x-coordinates of the extremes are ...
C: -(-4)/(2(4)) = 1/2
D: -(-16)/(2(2)) = 4 . . . . . matches the requirement
The appropriate choice is ...
f(x) = 2x^2 - 16x + 35
4 times 4=16 So in four days, Cheyrl traveled 16 miles.
