We are given order pairs : (2, 6), (3, 21), (4, 42), (5, 69)

The correct option is  D) f(x) = 3x^2 - 6.

If we plug x=2 we get

f(2) = 3(2)^2 - 6 = 3(4) -6 = 12-6 =6.   Represents (2,6)

If we plug x=3 we get

f(3) = 3(3)^2 - 6 = 3(9) -6 = 27-6 =21    Represents (4,21)

If we plug x=4 we get

f(4) = 3(4)^2 - 6 = 3(16) -6 = 48-6 =42.    Represents (4,42)

If we plug x=5 we get

f(5) = 3(5)^2 - 6 = 3(25) -6 = 75-6 =69.   Represents (5,69)

Therefore, D ) f(x) = 3x^2 - 6 is our correct option.

6 dogs are black, 5 dogs are white, and the rest are blue. If there are 15 dogs in total, how many are blue?
Bezzdna [24]

An airplane travels 800 miles with the wind in the same of time it takes to travel 650 miles against the wind. What is the speed
SOVA2 [1]

Answer:

90 mph

Step-by-step explanation:

Against wind DATA:

distance = 600 miles ; time = 5 hrs. ; rate = 600/5 = 120 mph

With wind DATA:

distance = 600 miles ; time = 2 hrs ; rate = 600/2 = 300 mph

Equations:

p + w = 300

p - w = 120

2p = 420

p = 210 mph (speed of the plane in still air)

Since p+w = 300, w = 300-210 = 90 mph (speed of the wind)
