A = r² π
254.469 = r² π
r² = 254.469 : 3.14159
r² = 81.00866
r = 9.0048
C = 2 r π = 2 * 9.0048 * 3.14159 = 56.55 units

What is the range of the function f(x) = 3x - 12 for the domain (-2, 2)?
Dmitry [639]

When x=-2

f(x) =3(-2) -12 =-6-12=-18

When x=2

f(x) = 3(2)-12=6-12=-6

So For the domain (-2,2)

Range of the function f(x) is (-18,-6)

So (-18 ,-6). is your answer.

Hope it helps....

The cost for each car entering President George Bush Turnpike at Beltline road is $0.75. The equation that represents this relat
vesna_86 [32]

From the definition of a function, a function associates every element of the domain to a unique element in the codomain.

In other words, if two elements are equal in the domain, then their images should also be equal.

Since, x represents the number of cars, we consider the universal set as N, the set of all natural numbers.

Let x, y ∈ N and x = y

Then, 0.75x = 0.75y

⇒ f(x) = f(y)

Therefore, images are equal, whenever elements are equal.

Hence, the function f(x) = 0.75x is a function. Also, note that the domain of the function is the set of all natural numbers and the range is the set of real numbers.

Would a teaspoon be a good way to measure the capacity of a milk carton
Natali [406]
No, a teaspoon is too small to measure the capacity of a milk carton. You would use a quart to measure the capacity of a gallon.

Hope this helps :)
