To find f(2), put 2 where the variable is, then do the arithmetic. It might be easier to factor out x^2:
f(x) = (-6x-4)·x^2
f(2) = (-6·2-4)·2^2
= -16·4
= -64
Then the ordered pair (x, f(x)) for x=2 is
B. (2, -64)
F(x)=2x^2-10
f(5)=2(5^2)-10
f(5)=2(25)-10
f(5)=50-10
f(5)=40

Answer:
claires orange juice is stronger
Step-by-step explanation:
(water:juice)
claire- 2.5:0.33
0.33 x 3 = 1
2.5 x 3 = 7.5
7.5:1 (claire uses 7.5 cups of water for every cup of orange juice concentrate
han- 1.66:0.25
0.25x4=1
1.66x4=6.64
6.64:1 (han uses 6.64 cups of water for every cup of orange juice concentrate)
