Description

Algebra Notes: variabili 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. 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....
