Y = x^2 -3
y = (x-3)(x+3)
For x-intercepts, y = 0
Therefore (x-3)(x+3) = 0
x intercepts are (3,0) and (-3,0)
The line of symmetry is x = 3+(-3) = 0
Vertex is on the line of symmetry
When x = 0, y = -1
Vertex = (0,-1)

Answer:
m +2m +(2m -6) = 19
Step-by-step explanation:
m = number of books sold on Monday.
2m = number of books sold on Tuesday, twice as many as Monday.
2m -6 = number of books sold on Wednesday, 6 fewer than Tuesday.
The total number of books sold on the three days gives the equation you're looking for:
m +2m +(2m -6) = 19
_____
<em>Additional comment</em>
Solving this gives ...
5m = 25 . . . . add 6
m = 5 . . . . . divide by 5
5, 10, and 4 books were sold on the three days.
