Answer: (-1, 4) is the vertex of the parabola.
To find the vertex when you are given the equation in vertex form, all you have to do is look at the letters k and h. They will tell you what the vertex is.
It is always (h, k)
There is only one trick in this problem. You have to change "(x + 1)" to "(x - (-1))" since the format of the equation requires "(x - h)".
This makes the h value -1 instead of 1.

Answer:
About 225 grams is 8 ounces
Step-by-step explanation:
The average is 4 3/4 km.
you would have to add the distance she ran for each day and then divide by the number of days she ran to find the average.
5 1/2 + 6 1/4 + 4 1/2 + 2 3/4 =19
19 (the total distance ran) divided by 4 (the number of days) = 4 3/4
