Alisa hopes to play beach volleyball in the olympics someday. she has convinced her parents to allow her to set up a beach volleyball court in their backyard. a standard volleyball court is 26 feet by 52 feet. she figures she will need the sand to be one foot deep. sand a is 60 lbs for $5 sand b is 150 lbs for $12 a. what's is the rate brand a is selling for? give rate and then specify the unit rate. b. which brand is offering the better value? explain.

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.
