Answer:
x=1
Step-by-step explanation:
X= means that it is the vertical line on that number, so x=1 would be the vertical lines going through 1, which would be in the middle of the parabola, thus having symmetry
The answer is gonna be Negative
Answer:
28
Step-by-step explanation:
So its a 50/50 chance for the coin to land on heads or tails, so we would divide 56 by 2
56/2 = 28
The axis of symmetry of a parabola in the form

is a vertical line

where k is the x coordinate of the vertex of the parabola.
The x coordinate of the vertex of the parabola is given by

which in your case is

So, the axis of symmetry is the line x=12.
