Answer:
The vertex of the function is 
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 
.
f(x) = x² - X + 2.
Quadratic equation with 
So
The vertex of the function is
This is in its simplest form.
Decimal form is 1.375
Answer:
The range of the given data set is 6.
Step-by-step explanation:
Range of the data set provides us with some basic information regarding spread of the data.
It is commonly used and quite easy to find.
First step is to arrange the values from the lowest to the highest.
It is already given arranged, so that will savd us some time.
Next step is simply subtracting the two values on the extremes, or, simply put, subtract the lowest from the highest value.
So, the range in this case would be 7-1=6.
