A website charges the same shipping fee on every order. The table shows the relationship between the cost of the items on the website, w, and the total cost including shipping, y.
Cost of Items (
$18
$35
$86
Total Cost (y)
$26
$43
$94
Complete the equation so that it models the relationship between the cost of the items on the
website, x, and the total cost including shipping, y. Enter your answer in the box.
y=+

let f (x ) is a function and c be a positive real number,   the graph of the function g (x ) = f (cx ) is represented as follows.

when, c > 1,   the function compresses it in the x - direction.

when, 0 < c < 1, the function stretches it.

the function is g ( x ) = (9x )2.

the heighest power of x in g ( x ) = (9x )2 is 2, so the parent function is square function.

the equation of parent function is f ( x ) = x 2 .

the function is g ( x ) = (9x )2 and the parent function is f ( x ) = x 2 .

so, the functions f and g have the following relationship.

g ( x ) = f ( 9x ).

compare the function g ( x ) = f ( 9x ) with g (x ) = f (cx ).

c = 9 ( > 1 ).

so, the function g (x ) = (9x )2 compresses it in the x - direction.
