Vertex Form

Front

Back

domain

Front

The set of input values of a function.

Back

y-intercept

Front

the point where the function crosses the y-axis, the x-value at this point is zero

Back

vertex of a parabola

Front

the maximum or minimum value, the highest or lowest point on a line graph.

Back

function

Front

For every input there is exactly one output

Back

reflection

Front

A transformation that "flips" a figure over a mirror or reflection line.

Back

maximum value

Front

When the vertex is the highest point, occurs when the parabola opens down

Back

Leading Coefficient

Front

The coefficient of the term with the highest degree

Back

vertex

Front

Either the minimum or maximum value of a function

Back

stretch/skinny

Front

a continuous or unbroken length, area, or expanse

Back

Quadratic Formula

Front

Back

horizontal translation

Front

A shift in which a plane figure moves horizontally (left/right)

Back

minimum value

Front

When the vertex is the lowest point, occurs when the parabola opens up

Back

Term

Front

A number, a variable, or the product of a number and a variable

Back

shrink/compress/fat

Front

to become reduced in size, amount, or value

Back

Factored Form

Front

Y=(x-r1)(x-r2)

Back

vertical translation

Front

A shift in which a plane figure moves vertically (up/down)

Back

Standard Form

Front

f(x)=ax^2+bx+c

Back

Transformation

Front

Includes shifting the parent function vertically, horizontally, compressing/fattening, stretching, or reflecting

Back

Degree of Polynomial

Front

The highest power of the variable in a polynomial

Back

linear

Front

a straight line, has a constant rate of change, has a degree of 1

Back

zero of a function

Front

a number that names the function equal to zero, also an x intercept

Back

Discriminant

Front

b²-4ac

Back

quadratic function

Front

A function where a,b,and c are real numbers and a ≠ 0, a function with a degree of two

Back

x-intercept

Front

the point where the function crosses the x-axis, the y-value at this point is zero

Back

parabola

Front

the graph of a quadratic function

Back

Constant

Front

a term without a variable

Back

axis of symmetry

Front

A line that divides a plane figure or a graph into two congruent reflected halves, always goes through the vertex

Back

degree

Front

A unit of measurement of angles

Back

exponential

Front

Growth whose rate becomes ever more rapid in proportion to the growing total number or size.
