The equation y = -x2 - 8x - 18 is shown by graph
the equation y = x2 - 4x + 7 is shown by graph
the equation y = x + 5 is shown by graph
the equation y=-3x - 6 is shown by graph

y = -x2 - 8x - 18 ⇒ c

y = x2 - 4x + 7 ⇒ a

y = x + 5 ⇒ c

y=-3x - 6 ⇒ b

Step-by-step explanation:

the pictures show it
