Quadratic graph formula for concave positive

Y = x^2

Quadratic graph formula for concave negative

Y = -x^2

Axis of symmetry in a parabola

The vertical line that divides the parabola into two symmetrical parts.

Vertex of a parabola

The turning point of the parabola, which can be a minimum or maximum point.

Roots of a parabola

The x-intercepts, or points where the parabola intersects the x-axis.

Y intercept of a parabola

The point where the parabola touches the y-axis, found by substituting x=0 into the equation.

Formula for positive exponential growth

Y = a^x, always passing through the point (0,1).

Formula for negative exponential decay

Y = a^-x, also passing through the point (0,1).

Composite volume

The volume of a shape made up of two or more simple shapes combined.

SOH CAH TOA

A mnemonic for remembering the definitions of sine (SOH), cosine (CAH), and tangent (TOA) in trigonometry.

Pythagorean theorem

A fundamental relation in Euclidean geometry among the three sides of a right triangle: a^2 + b^2 = c^2.

Measures of center

Values that summarize a set of data, including mean, median, and mode.

Standard deviation

A measure of the amount of variation or dispersion in a set of values.

Cumulative frequency

A measure that sums the frequencies of the data up to a given point.

Negative skew

A distribution where the tail on the left side is longer or fatter than the right side.

Box plot

A graphical representation of data that shows the distribution based on a five-number summary: minimum, first quartile, median, third quartile, and maximum.
