Across
Using numbers, variables, and operation symbols
x-intercept of the graph of that function where "y" is 0 (zero). Also called the root of a function.
A function that can be written in the form f(x) = ax2+bx+c, where a,b,and c are real numbers and a ≠ 0(Multiple words no spaces)
Two or more linear equations using the same variables.(Multiple words no spaces)
coefficient A number multiplied by a variable in an algebraic expression.
An algebraic expression with only one term.
An equation that has no operations other than addition, subtraction, and multiplication of a variable by a constant. Graph result is a straight line.(Multiple words, no spaces)
A relation in which each element of the domain is paired with exactly one element in the range.
A letter or symbol used to represent one or more numbers.
Down
The sum and/or difference of one or more monomials. (ex. 3x^4, 5x+7)
A polynomial with exactly two terms.
A rule for evaluating expressions: first perform the operations in parentheses, then compute powers and roots, then perform all multiplication and division from left to right, and then perform all addition and subtraction from left to right.(Multiple words, no spaces
A property indicating a special way in which multiplication is applied to addition of two or more numbers in which each term inside a set of parentheses can be multiplied by a factor outside the parentheses, such as a(b + c) = ab + ac(multiple words, no spaces)
A pair of numbers used to locate a point on a coordinate plane; the first number tells how far to move horizontally (x) and the second number tells how far to move vertically (y).(Multiple wordsm no spaces)
the vertical axis on a coordinate plane...top to bottom.(two word no space)
x coordinate of a point where a graph crosses the x axis/ y coordinate of this point is zero. (two word no space)
The name of the graph of a quadratic function that has the shape of two curved branches.
A measure of the steepness of a line. Given two points with coordinates (X1,Y1) and (x2,y2) on a line the slope, m, of the line is given m = rise/run= y2-y1/x2-x1
