solution

,factor - CORRECT ANSWER- a number or expression that is multiplied by another number or
expression to get a product
monomial - CORRECT ANSWER- a number or a product of numbers and variables with whole-
number exponents, or a polynomial with one term
substitution method - CORRECT ANSWER- A method used to solve systems of equations by
solving an equation for one variable and substituting the resulting expression into the other
equation(s)
system of linear equations - CORRECT ANSWER- a system of equations in which all of the
equations are linear
correlation - CORRECT ANSWER- a measure of the strength an direction of the relationship
between two variables or data sets
correlation coefficient - CORRECT ANSWER- a number r greater than or equal to -1 and less
than or equal to 1, that describes how closely the points in a scatter plot cluster around the line
of best fit.
linear regression - CORRECT ANSWER- a statistical method used to fit a linear model to a given
data set
residual - CORRECT ANSWER- the signed vertical distance between a data point and a line of fit
X-Intercept - CORRECT ANSWER- The x-coordinate(s) of the point(s) where a graph intersects
the x-axis.
,Y-Intercept - CORRECT ANSWER- The y-coordinate(s) of the point(s) where a graph intersects
the y-axis.
Linear Function - CORRECT ANSWER- A function that can be written in the form y=mx+b,
where x is the independent variable and m and b are real numbers. Its graph is a line.
Rate - CORRECT ANSWER- A ratio that compares two quantities measured in different units.
Rate of Change - CORRECT ANSWER- A ratio that compares the amount of change in a
dependent variable to the amount of change in an independent variable.
Slope - CORRECT ANSWER- A measure of the steepness of a line.
Exponent - CORRECT ANSWER- The number that indicates how many times the base in a
power is used as a factor.
Exponential Expressions - CORRECT ANSWER- An algebraic expression in which the variable is
in an exponent with a fixed number as the base.
Exponential Function - CORRECT ANSWER- A function in the form f(x)=ab^x where a and b are
real numbers, a does not equal zero, b>0, and b does not equal 1.
Perfect Square - CORRECT ANSWER- A number whose positive square root is a whole number.
Exponential Growth - CORRECT ANSWER- An exponential function in the form y=a(1+r)^t,
where r is the rate of growth, a is the initial amount and t is the time.
, Exponential Decay - CORRECT ANSWER- An exponential function in this form, where r is the
rate of decay, a is the initial amount and t is the time.
Base - CORRECT ANSWER- The number in a power that is used as a factor.
Half-life - CORRECT ANSWER- The half-life of a substance is the time it takes for one-half of the
substance to decay into another substance.
arithmetic sequence - CORRECT ANSWER- A sequence whose successive terms differ by the
same nonzero number, called the "common difference".
common difference - CORRECT ANSWER- In an arithmetic sequence, the nonzero constant
difference of any term and the previous term.
dependent variable - CORRECT ANSWER- The output of a function; a variable whose value
depends on the value of the input, or independent variable.
domain - CORRECT ANSWER- The set of all inputs (generally x-values) of a relation or function.
function - CORRECT ANSWER- A relation in which ever domain value is paired with exactly one
range value.
function notation - CORRECT ANSWER- If x is the independent variable and y is the dependent
variable, than the function can be written as f(x), where f names the function.
independent variable - CORRECT ANSWER- The input of a function, a variable whose value
determines the value of the output, or dependent variable.
