Answer:
The answer is "Choice B, C, and F is correct".
Step-by-step explanation:
The following are choices, which is missing in the question, that can be defined as follows:
A) {x| x ≥ 3} is the domain.
B) The set shall be {y| y ≥ –1}.
C) over the interval (–∞, 3), is the function, that decreases.
D) it's over the duration the function increases its value, that is (–1, ∞).
E) The symmetry axis will be x = – 1.
F) vertex is (3, – 1).
- In choice A, It is incorrect even though f is the domain, which is all true numbers because it has a quadrant function.
- In choice B, it is correct.
- In choice C, It is valid because it was a parable open with vertex so if we exploded view f (3, -1). Because as value opens up, its value with x from-∞ to 3 drops while it goes up from increasing from 3 to ∞.
- In choice D, It is wrong since we have just said f decreases from-∞ to 3. Therefore, f decreases from -1 to 3, too. Therefore, f doesn't grow from -1 to ∞.
- In choice E, It is incorrect because the symmetry axis is x = 3.
- In choice F, it is true.
The situation that is a function is: C. The weight of a package and the cost of postage.
<h3>What is a Function?</h3>
A function can be described as a relation whereby there can only be one exact possible output value (dependent variable) for every input value (independent variable) in the relation. This means, no input value has two different output values. However, two different input values can have the same output value.
In a function, the output value is dependent on the input value.
For example, the cost of postage (output) is dependent on the weight of a package (input).
Therefore, the situation that is a function is: C. The weight of a package and the cost of postage.
