Isae says that a step graph does not represent a function because the graph is not connected. alex says that it does represent a function because there is only one y for every x. who is correct and why? a. misae is correct because she is applying the definition of a function. c. neither is correct. b. alex is correct because he is applying the definition of a function.

b. Alex is correct because he is applying the definition of a function.

Step-by-step explanation:

Let's see the definition of function.

A function relates each element of a set  with exactly one element of another set.

A step function is a function but it disconnect in some interval but still it is a function since it has unique out put for each input.

Therefore, Alex  is correct because he is applying the definition of function.

Hope you will understand the concept.

Thank you.

No sadly you are incorrect the answer is a right triangle because you can not have a right triangle as an acute triangle

Step-by-step explanation:

30,60,90

90 is an right triangle

The rest are acute but 90 is bigger so the correct answer would be right triangle.
