function review Flashcards
the variable in a function whose value does not depend on the value of the other variable
independent variable
the variable in a function whose value depends on the value of the other variable
dependent variable
a method of writing a function in which the dependent variable is written in the form f(x). The independent variable,x, is placed into the parentheses
function notation
the y-coordinate of the point where a line crosses the y-axis
y-intercept
the x-coordinate of the point where a line crosses the x-axis
x-intercept
used in a geometric series. is a ratio of a term and the previous term
common ratio
the difference between each number in an arithmetic sequences
common difference
the y-value of the vertex of a parabola the opens down
maximum value
the y-value of a vertex of a parabola that opens up
minimum value
a line drawn through the graph of a function that divides the graph into two halves that are reflections of each other
axis of symmetry
when one shape becomes exactly like another if you flip, slide or turn it.
symmetry
the rate of change of a linear function is equal to the slope of the graph of the function
rate of change
the point where the parabola changes direction.
vertex
the shape of a graph of a quadratic function.
parabola
an exponential function that is increasing
growth
