A..... is a set of ordered pairs in which no two ordered pairs have
function
The .... of a relation is the set of all Örst coordinates of the ordered pairs
domain
The ..... of a relation is the set of all second coordinates of the ordered pairs.
range
Since y depends on x, we call x the .......... variable and the y the dependent variable.
independent
If a vertical line intersects a graph in more than one point, the graph is ...the graph of a function
not
The ............f (x) denotes a function
symbol
The ...... .......... is the average rate of change between two points
di§erence quotient
The form y = mx + b called .... intercept form
slope
letter ....... , represents the slope
m
letter ....., represents the y‐intercept
b
A ...... is a correspondence between two sets .
relation
The independent variable is also called the ....of the function.
argument
When a function f i sdefined by an equation in x and y, we say that the function f is given ........
implicitly
If it is possible to solve the equation for y in term sof x, then we say y=f(x) and the function is .......
