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
Im on sure but probably 0.75
Answer:
1 is 9 sq units
2 is 12
3 is 24cm^2
Step-by-step explanation:
5x = 20...where x = number of months
x = 20/5
x = 4...it would take Tom 4 months to save $20
