35 terms

variables

x, y, or any letter that can represent a number that we don't know

coefficient

a number that is in front of a variable

A number multiplied by a variable.

A number multiplied by a variable.

Function

A relation for which each output has only one input. Can be tested on the coordinate plane with the vertical line test

linear

Equations that does not have any variables with an exponent. They form a lie when graphed.

quadratic parent function

y=x^2

axis of symmetry

A line that divides a parabola into two congruent reflected halves.

vertex

maximum or minimum of a quadratic

y-intercept

A place where a function crosses the y-axis represented by b in the formula y=mx+b.

absolute value

The distance a number is from zero

range

All possible y values of a function

point slope form

domain

All possible x values of a function

whole numbers

Natural numbers and zero

Not negative or decimals

Not negative or decimals

scientific notation

One number is in front of the decimal. It will be multiplied by 10 to some power.

zero exponent

expression

terms

integers

whole numbers and their negatives

coordinate plane

A two-dimensional number line where the vertical line is called the y-axis and the horizontal is called the x-axis. These lines are perpendicular and intersect at their zero points called the origin.

negative exponent

Negative is the opposite of positive and division is the opposite of multiplication, so a number with a negative exponent should be moved to the denominator of a fraction and the exponent switched to positive.

exponential form

5*5

irrational numbers

order of operations

Grouping symbols, Exponents, Multiplication, Division, Addition, Subtraction

rational number

1/2, .75, -2.2, 9

real number

all rational and irrational numbers

x-intercept

A place where a function crosses the x-axis represented by x in the formula y=mx+b.

standard form

slope

steepness of a line

function notation

examples: f(x)=3x, g(x)=5x+2 , h(x)=10

slope intercept form

natural numbers

parabola

U-shaped curve formed when you graph a quadratic function

vertex of a parabola

highest or lowest point in a parabola

quadratic function

degree of 2

linear equation

forms a line when graphed
