A function is a relation where each input value is assigned to one output value.

The
of a function is the set of all input values, or x-values, for which the function is defined.

The
of a function is the set of all output values, or y-values, for which the function is defined.

To write the equation y = ax + b in function notation, substitute
for y.

Step-by-step explanation:

A function is a relation where each input value is assigned to exactly  one output value.  The  domain  of a function is the set of all input values, or x-values, for which the function is defined.  The range  of a function is the set of all output values, or y-values, for which the function is defined.  To write the equation y = ax + b in function notation, substitute f(x) for y.

(I did this on Plato/Edmentum and got it correct!)

answer: 21$

step-by-step explanation:

$42 / $14 = 3   (ratio 3: 1)

$7 x 3 = $21
