A function is a relationship that each input (element of the domain) is paired with exactly one output (element in the range).
In function notation, f(x), the “x” is the input and the entire “f(x)” represents an output.
That means the last two options are wrong. They’re purposely switched up in what they say.
The correct answer is the second one, because that one is saying “each input will be paired with exactly one output.”
A triangle a can’t have more than 1 obtuse angle because all angles have to equal 180 degrees, and an obtuse angle is larger then 90 degrees. If it had more than 1 obtuse angle, the angles wouldn’t equal 180 degrees and you wouldn’t be able to make a third angle.
Answer:
No.

A regular polygon has all sides and angles congruent. This is not possible with a concave polygon. If the sides are congruent in a concave polygon the angles are not congruent.
