Raw coffee loses 12% of its weight when it is roasted. how much raw coffee will make 33 lb of roasted coffee? '

The amount of coffee will be 37.5 lb

Let x be the amount of coffee

Now

According to the situation

Taking the ratios of quantities

0.88x = 33

Dividing both sides by 0.88

0.88x/0.88 = 33/0.88

We get

x = 37.5 lb

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.
