Answer:
Mean: 5
Median: 5
Mode: 2
Range: 7
Step-by-step explanation:
We find the mean by adding all the numbers together to get 45. Then we divide the 45 by the amount of numbers in the set, for this one it is 9. 45 divided by 9 equals 5.
To find the median we put the numbers in the set in order from least to greatest. Next, we find the middle number. median=5
To find the mode we find the number repeated the most. In this set the number that repeats the most is 2.
Range is found by subtracting the largest number and the smallest number. 9-2=7

Answer:
Step-by-step explanation:
we know that
Is the equation of a vertical parabola written in vertex form
where
(h,k) is the vertex
a is the leading coefficient
In this problem we have
The vertex is the point (-1,4)
so
substitute
Find the value of a
we have the ordered pair (0,3)
substitute the value of x and the value of y in the quadratic equation and solve for a
therefore
