Which answer is not in scientific notation? a. 6 · 10^25b. 2.01 · 10^-2c. 1.3 · 10^-4d. 0.5 · 10^3

D. 0.5 · 10^3

Step-by-step explanation:

is in the form

a * 10 ^b

Scientific notation has one number ( not zero)  before the decimal and b is an integer

A. 6 · 10^25   True

B. 2.01 · 10^-2   True

C. 1.3 · 10^-4   True

D. 0.5 · 10^3   False  this does not have one number before the decimal)

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.
