During a 7-year period, the amounts (in millions of dollars) spent each year on buying New vehicles (N) and Used vehicles (U) by United States residents are modeled by the equations below: N = 0.8t2 + 0.4t + 12
U = -0.43t2 + 1.8t + 29
Write a polynomial in standard form that represents the total amount spent each year on buying new and used vehicles in the 7-year period.

answer:

a=9

the answer is a beach is the best place to be

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.
