The vertex form of a quadratic function is f(x) = a(x - h)2 + k. What is the vertex of each function? Match the function

rule with the coordinates of its vertex.

f(x) = 9(x - 5)2 + 6

(5.-9)

f(x) = 9(x + 5)2 - 6

(-9,-5)

f(x) = 6(x + 9)2 - 5

(-5, -6)

f(x) = 6(x - 5)2 - 9

(5,6)

f(x) = 5(x - 6)2 +9

(6,9)

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9
