Step-by-step explanation:
The coefficent of the x variable is b.
The formula for the period is
Here, b is 6 so we have
So the period is pi/3, or 60 degrees
All of the points in the picture are on the same line. Fine the slope of the line.

Remember (Soh) (Cah) (Toa). CSC is just the inverse of sine.
something noteworthy is that the independent and squared variable in this case will be the "x", namely the graph of that quadratic is a vertical parabola.
so the parabola has solutions at x = -2 and x = 4, and its vertex will be half-way between those two guys, namely at x = 1.
since this is a vertical parabola, its axis of symmetry, the line that splits its into twin sides, will be a vertical line, and it'll be the x-coordinate of the vertex, since the vertex hasa a coordinate of x = 1, then the axis of symmetry is the vertical line of x = 1.
