11. Read the following word problem, then choose which linear equation models the problem. The sum of the ages of an older sibling and a younger sibling is 16. Four years from now, the age of the younger sibling will be the same as the age of the older sibling was two years ago. Find the present age of each sibling.
A. x - 4 = 14 + x
B. 4x = 14 - x + 16
C. x + 14 - x = 16 + 2
D. x + 4 = 14 - x

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.
