the graph of f(x) can be compressed vertically and shifted to the left to produce the graph of g(x). if f(x) =x^3, which of the following could be the equation of g(x)?

Respuesta :

Answer: [tex]B.\ g(x)=\frac{1}{4}(x+3)^3[/tex]

Step-by-step explanation:

The misssing options are:

[tex]A.\ g(x)=4(x-3)^3\\\\B.\ g(x)=\frac{1}{4}(x+3)^3\\\\C.\ g(x)=4(x+3)^3\\\\D.\ g(x)=\frac{1}{4}(x-3)^3[/tex]

Some transformations for a function f(x) are shown below:

1. If [tex]f(x-k)[/tex], the function is shifted right "k" units.

2. If [tex]f(+k)[/tex], the function is shifted left "k" units.

3. If [tex]bf(x)[/tex] and [tex]b>1[/tex], the function is stretched vertically by a factor of "b".

4. If [tex]bf(x)[/tex] and [tex]0<b<1[/tex], the function is compressed vertically by a factor of "b".

In this case, you know that the parent function f(x) is:

[tex]f(x)=x^3[/tex]

If the graph of the function g(x) is obtained by compressing vertically and shifting the function f(x) to the left, then:

[tex]g(x)=bf(x+k)[/tex] and [tex]0<b<1[/tex]

Based on this, you can identify that the following function could be the equation of the g(x):

[tex]g(x)=\frac{1}{4}(x+3)^3[/tex]
