Answer 1

Answer:

graph A

Step-by-step explanation:

direction: opens up

vertex: (3,-16)

focus: (3,-64/4)

axis of symmetry: x=3

directrix: y= -64/4

x=1, y=-12

x=2, y= y=-15

x=3, y=-16

x=4, y=-15

x=5, y=-12

hope this helps :)

Answer 2

Answer:

Graph A

Step-by-step explanation:

$y = {x}^{2} - 6x - 7 \\ plug \: y = 0 \\ {x}^{2} - 6x - 7 = 0 \\ {x}^{2} - 6x + 9 = 7 + 9 \\ (x - 3)^{2} = 16 \\ (x - 3) = \pm 4 \\ x = 4 + 3 \: or \: x = - 4 + 3 \\ x = 7 \: or \: x = - 1$

Its mean graph should intersect x axis at x = 7 and x = - 1. This everything is satisfied by graph A.
