Hello! Remember you have to write complete questions in order to get good and exact answers. Here I'll assume the graphed function comes from:
So this is the equation of a parabola that opens upward and whose vertex lies on the point:
The graph of this function is shown below. Which is true regarding the graphed function f(x)?
- It is true that the domain is the set of all real numbers because this is a polynomial function.
- It is true that the range is the set of all real numbers such that y ≥ 5
- It is true that this parabola opens upward
- It is true that it doesn't cut the x-axis
Question is Incomplete; Complete question is given below;
James and Amy played 12 games of checkers last week. This week they played 7 games on Monday and 2 games on Wednesday.James and Amy play 3 more games. They have played the same number of games as last week. Fill in the blanks to make the equation true. Use +,-, or =. 12_7_2_3 Explain how you chose the symbols.
Answer:
12<u> = </u>7<u> + </u>2<u> + </u>3
Step-by-step explanation:
Given:
Number of games played last week = 12
Number of games played on Monday this week = 7
Number of games played on Wednesday this week = 2
Also given:
James and Amy play 3 more games.
So Number of games played more = 3
We need to fill in the blanks 12 __ 7__2__3 with signs '+', '-','='.
Solution:
It is given that they have played the same number of games as last week.
So we can say that;
Number of games played last week is equal to Number of games played on Monday this week plus Number of games played on Wednesday this week plus Number of games played more.
framing in equation form we get;
Hence we have fill the blanks as 12<u> = </u>7<u> + </u>2<u> + </u>3.
