Given: <span>y = x^2 + 6x - 5. Then a = 1, b = 6 and c = -5.
The x-coord. of the vertex is given by x = -b / (2a), which here is x = -6 / (2*1) = -3.
Use the given formula </span><span>y = x^2 + 6x - 5 to find the value of y when x = -3:
y = (-3)^2 + 6(-3) - 5 = 9 - 18 - 5 = -14
Then the vertex is (-3, -14).</span>
You flip the inequality.
Example: if x > -y and you divide both sides by (-1) then you flip the inequality so: -x < y

Given the following data set 2,3,1,6,1,1,1,0,2,4,5,1,2,2,3<br>Mean <br>Median <br>Range<br>Mid range
igomit [66]
Answer:
mean: 34/15=2.27
median: 2
range: highest-lowest...... 6-0=6
mid range: high + low divided by 2
6+0=6/2=3
