Un incendio inicio a las 10am incinerando un área de un metro cuadrado; a las dos horas el incendio había consumido 9 metros cuadrados; a las 5 horas ya había devastado 243 metros cuadrados. Una ecuación que puede modelar el área devastada por el incendio en función de la cantidad t de horas transcurridas es: a. A(t) = 3t
b. A(t) = t ^3

c. A(t) = 3^t
d. A(t) = 3t + 1

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.
