I think the correct answer from the choices listed above is option D. For the function f(x) = (x − 2)2 + 4, the <span>vertex is (2, 4), the domain is all real numbers, and the range is y ≥ 4. The domain is all x-values available for the function and the range are the y values and in this case it should be greater than or equal to 4. Hope this answers the question.</span>
16:12 and 4:3 since you multiply two in both sides to get 16:12 so they're equivalent and then you divide 2 on both sides to get 4:3 so that's equivalent

Answer:
Hi, There! FrozenVines Here!
I'm here to help you Understand Better So Let's go-
20:24 is My Answer
Step-by-step explanation:
y = kx, where k is the constant of proportionality. In other words, these quantities always maintain the same ratio
proportion is an equation with a ratio on each side. It is a statement that two ratios are equal.
For example 2/5 is Equal to 4/10 this Would be A Example Of a Proportional relationship!
Answer: the vertex is (12,−144)
Step-by-step explanation:
Answer:
113.04
Step-by-step explanation:
The formula is pie × radius × radius pie=3.14 so 3.14 × 6 × 6 = 113.04
