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

step-by-step explanation:

what i would say the best answer is a. 40.5

the answer would be d.

step-by-step explanation:

move all variables to the left side and all constants to the right side

(x−3)^2+(y−1)^2=16

this is the form of a circle. use this form to determine the center and radius of the circle.

( x − h ) 2 + ( y − k ) 2 = r 2

match the values in this circle to those of the standard form. the variable   r   represents the radius of the circle,   h   represents the x-offset from the origin, and   k   represents the y-offset from origin.

r = 4

h = 3

k = 1

the center of the circle is found at   ( h , k ) .

center:   ( 3 , 1 )

these values represent the important values for graphing and analyzing a circle.

center:   ( 3 , 1 ).

radius:   4
