Algebra Flashcards

7189607389	variables	x, y, or any letter that can represent a number that we don't know	0
7189607390	coefficient	a number that is in front of a variable A number multiplied by a variable.	1
7189607391	Function	A relation for which each output has only one input. Can be tested on the coordinate plane with the vertical line test	2
7189607392	linear	Equations that does not have any variables with an exponent. They form a lie when graphed.	3
7189607393	quadratic parent function	y=x^2	4
7189607394	axis of symmetry	A line that divides a parabola into two congruent reflected halves.	5
7189607395	vertex	maximum or minimum of a quadratic	6
7189607396	y-intercept	A place where a function crosses the y-axis represented by b in the formula y=mx+b.	7
7189607397	absolute value	The distance a number is from zero	8
7189607398	range	All possible y values of a function	9
7189607399	point slope form		10
7189607400	domain	All possible x values of a function	11
7189607401	whole numbers	Natural numbers and zero Not negative or decimals	12
7189607402	scientific notation	One number is in front of the decimal. It will be multiplied by 10 to some power.	13
7189607403	zero exponent		14
7189607404	expression		15
7189607405	terms		16
7189607406	integers	whole numbers and their negatives	17
7189607407	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.	18
7189607408	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.	19
7189607409	exponential form	5*5	20
7189607410	irrational numbers		21
7189607411	order of operations	Grouping symbols, Exponents, Multiplication, Division, Addition, Subtraction	22
7189607412	rational number	1/2, .75, -2.2, 9	23
7189607413	real number	all rational and irrational numbers	24
7189607414	x-intercept	A place where a function crosses the x-axis represented by x in the formula y=mx+b.	25
7189607415	standard form		26
7189607416	slope	steepness of a line	27
7189607417	function notation	examples: f(x)=3x, g(x)=5x+2 , h(x)=10	28
7189607418	slope intercept form		29
7189607419	natural numbers		30
7189607420	parabola	U-shaped curve formed when you graph a quadratic function	31
7189607421	vertex of a parabola	highest or lowest point in a parabola	32
7189607422	quadratic function	degree of 2	33
7189607423	linear equation	forms a line when graphed	34
