Answer:

D

Step-by-step explanation:

A coordinate grid is shown from negative 5 to 0 to 5 on both x- and y-axes. A polygon ABCD has A at ordered pair (2, 3), B at ordered pair (4, 4), C at ordered pair (3, 1), D at ordered pair (2, 1). A polygon A'B'C'D' has A' at ordered pair (-1, 3), B' at ordered pair (-3, 4), C' at ordered pair (-2, 1), D' at ordered pair (-1, 1).

Which of the following sequences of transformations is used to obtain figure A'B'C'D' from figure ABCD? (1 point)

a ) Counterclockwise rotation by 90 degrees about the origin followed by a translation to the right by 1 unit

b) Counterclockwise rotation by 90 degrees about the origin followed by a translation to the left by 1 unit

c ) Reflection about the x-axis followed by a translation to the left by 1 unit

d ) Reflection about the y-axis followed by a translation to the right by 1 unit

Suppose f(x) = x^2 and

SpyIntel [72]

Given:

The two functions are:

$f(x)=x^2$

$g(x)=\left(\dfrac{1}{3}x\right)^2$

To find:

The statement that best compares the graph of g(x) with the graph of f(x).

Solution:

The horizontal stretch is defined as:

$g(x)=f(kx)$ ...(i)

If $0$ , the function f(x) is horizontally stretched by factor $\dfrac{1}{k}$ .

If $k>1$ , the function f(x) is horizontally compressed by factor $\dfrac{1}{k}$ .

We have,

$f(x)=x^2$

$g(x)=\left(\dfrac{1}{3}x\right)^2$

Using these functions, we get

$g(x)=f\left(\dfrac{1}{3}x\right)$ ...(ii)

On comparing (i) and (ii), we get

$k=\dfrac{1}{3}$

Since $0$ , the function f(x) is horizontally stretched by factor $\dfrac{1}{\frac{1}{3}}=3$ .

Hence, the correct option is D.
