Answer:
Step-by-step explanation:
The function has the vertex at
.
Since , the graph of the function is a maximum graph.
The highest y-value is the y-coordinate of the vertex which is 5.
Therefore the range is {}
Therefore the correct answer is B.
Answer:
As the model is shown below.
As per model a thing is divided into five parts.There are three things and each one of them is being divided into five equal parts.
The value of fifth part of each of them is 1/5.
If we consider each part of a thing as one,
So, total number of parts = 15
Total thing=3
So, the answer of the above model is 3÷ 15.
Out of all the options which are 15÷15 , 3÷115 , 3÷15, 15÷15 →3÷15 is correct.
