Answer:

Step-by-step explanation:
There are many methods to find the vertex of a quadratic function. The method that I will show you is by using the roots of the function
In the case of this function, the roots are
..
The vertex of a function will always be directly between these roots. The number that is directly between -1 and -3 is -2. This means that the x-value of our vertex is -2.
Now that we have the x-value, we can plug this into the function in order to get our y-value.

We have found that our y-value is -2. This means that the coordinates of the vertex are 
Answer: 0.25 percent.
Step-by-step explanation:
You know that you have 800 pages. So, 2 out of 800 is 0.25 percent.
the slope goes by several names
• average rate of change
• rate of change
• deltaY over deltaX
• Δy over Δx
• rise over run
• gradient
• constant of proportionality
however, is the same cat wearing different costumes.
well, to get it all we need is two points, say hmmm let's use (-1 , -7) and (7 , 25)
