1. Parabola's equation is y = a(x + b)^2 + c, where (b, c) is the vertex.
2. We have y = a(x - 3)^2 + 1
3. Take everything to the left side:
-a(x - 3)^2 + y - 1 = 0
That's the standard equation. Hope this helps! :)

Step-by-step explanation:
you just simply divide. i cant really explain it other than that.
Answer:
zeros: -11 , 7
Line of symmetry: x = -2
Step-by-step explanation:
y = 2x² + 8x - 154 = 2*(x² + 4x - 77) = 2*(x+11)(x-7)
y = 0
x = - 11 or x = 7
line of symmetry: x = 1/2 (-11 + 7) = -2
2x² + 8x - 154 = 2*(x² + 4x +4) - 162 = 2 * (x+2)² - 162
vertex (h , k): h = -2 , k = -162
Line of symmetry: x = -2
S greater than or equal to 10
Answer:
AB = 9
Step-by-step explanation:
Given that line, l is a perpendicular bisector of line segment AC. It intersects line segment AC at point B.
So, we can conclude that AB = BC ............ (1)
Also given that the length of line segment BC is 9.
Now, from equation (1) we can say that, AB = 9.
Therefore, the length of segment AB is 9. (Answer)
