This Question:... 7 of 14 (3 complete) This Test: 10 Question Help Karl and Leonard want to make perfume. In order to get the right balance of ingredients for their tastes they bought 3 ounces of rose oil at $4.19 per ounce, 5 ounces of ginger essence for $3.18 per ounce, and 3 ounces of black currant essence for $4.36 per ounce. Determine the cost per ounce of the perfume. The cost per ounce of the perfume is $ (Round to the nearest cent.)​

the answer is d

step-by-step explanation:

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.
