General Math 1
having the same value
the ratio of the vertical change to the horizontal change, the steepness of a line
a linear function with an equation in the form y=kx
a function of the form y = ax^2 + bx + c, where a is not 0. The graph of this function is a parabola.
quadratic function
a function that repeatedly multiplies an initial amount by the same positive number, in the form y=ab^x
exponential function
a graph composed of isolated points
to rewrite an expression as simply as possible
two or more linear equations using the same variables
a linear function with an equation in the form y=kx
the line that divides a parabola into two matching halves
Axis of Symmetry
a line that the graph of a function gets close to but never touches
the method used to determine if a relation is a function or not.
all possible x values of a function and all possible y values of a function
the x-coordinate of a point where a graph crosses the x-axis
an x-intercept of the graph of a function
the highest or lowest point on a parabola. The axis of symmetry intersects the parabolas at this point.
a situation modeled with a function of the form y=ab^x, where 0 < b < 1 or b>1
put together (add)
a mathematical phrase that combines numbers and/or variables using mathematical operations
the y-corrdinate of a point where a graph crosses the y-axis
the most accurate trend line on a scatter plot showing the relationship between two sets of data
the y-coordinate of the vertex of a parabola that opens downward or the y-coordinate of the vertex of a parabola that opens upward
to decrease in value over time
a shift of a graph up/down or left/right
a relation that assigns exactly one value in the range to each value of the domain
a number from -1 to 1 that tells you how closely the equation of the line of best fit models the data
any ordered pair in a system that makes all the equations of that system true (point of intersection)
solution of a system of linear equations
a number or expression you multiply to get a product
1 minus the percent rate of change, written as decimal, for an exponential decay situation
symbol that say two values are not equal
a graph that is unbroken
when a change in one quantity causes a change in a second quantity. A correlation between quantities does not always mean causation
two or more linear inequalities using the same variables
system of linear inequalities
set of x-values that make the quadratic equation equal zero
1 plus the percent rate of change, written as a decimal, for an exponential growth situation
to write a function rule using the symbol f(x) in place of y
