Answer:
D. (3. —1)
Step-by-step explanation:
Vertex of a quadratic function:
Suppose we have a quadratic function in the following format:
It's vertex is the point 
In which
Where
If a<0, the vertex is a maximum point, that is, the maximum value happens at 
, and it's value is 
.
Turning point of a quadratic function:
The turning point of a quadratic function is the vertex.
y = x2 — 6x + 8
This means that 
Now, we find the vertex.
(x,y) = (3,-1), and the correct answer is given by option D.
Answer:
The total would come out to $28.50
The circle graph is usually used to show proportions of a whole.
The Venn Diagram is used to represent the relationship between two or more collection of objects.
The double bar graph is used to compare two variables over a period of time.
The line graph is used to compare the trends of a variable over a period of time.
Therefore, the <span>graphical representation that would best display the number of points a home team and a visitor’s team scored in each game this season is the double bar graph.</span>
