Terms in this set (...)

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.
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
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
