PLEASE HELP ASAPPP The safety inspector notes that Ray also needs to plan for a vertical ladder through the center of the coaster's parabolic shape for access to the coaster to perform safety repairs. Find the vertex and the equation for the axis of symmetry of the parabola, showing your work, so Ray can include it in his coaster plan.
f(x) = -x2 - 6x

= 3(x^2 + 3x) + 12 = 3(x+1.5)^2 +5.25 the        

vertex is at (0,5.25) when x = -1.5

axis of symmetry then lies in x = -1.5

Step-by-step explanation:i think its right

#15. square

step-by-step explanation:

because quadrilatural (idk how to spell it) means somthing that is not 3d or like, equal sides (or somthing like that   you know what i meanz)

hope this halps!

bai!
