The symbol '^' means "to the power of" so that B2 is written as B^2. The '/' symbol is a fraction bar, so that the fraction "two-thirds" is written 2 / 3. Remember, the exponent only belongs to the number it is directly attached to. In the term 7a^3 b^4 the exponent 3 only goes with the 'a'

If A is positive, the parabola opens upwards.
If A is negative, the parabola opens upwards.
If A is zero, the parabola opens to the side.

There are two vertex on every parabola.
The axis of symmetry tells you where the quadratic crosses the x-axis.
An x-y-table only helps you to graph an equation sometimes.
The vertex is the highest or lowest point of a parabola.

The discriminant is b^2 -4ac
The vertex formula is -2a / b
Every x-intercept has a y-coordinate of zero.
The origin is where the x-axis and the y-axis meet.

H = -16t^2 + vt + s
H = -16t^2 - 245t + 3
H = 16t^2 + 245t + 3
H = -16t^2 + 3t + 245
H = -16t^2 + 245t + 3
