Respuesta :

3 units left

2 units up

Answer:

3 unit left and 2 unit up.

Step-by-step explanation:

Given : [tex]f(x)= \log_2(x + 3)+2[/tex] as a transformation of the graph of [tex]g(x) = \log_2x[/tex]

To find : Which best describes the graph transformation?

Solution :

The parent function [tex]g(x)=\log_2x[/tex]

with the vertex (1,0)

And the graph of [tex]f(x)=\log_2(x + 3)+2[/tex]  

with the vertex (-2.75,0)

The graph of f(x) is the translation of g(x)

Transformation to the left,

f(x)→f(x+b) , the graph of f(x) is shifted towards left by b unit.

Same as the graph g(x) is shifted towards left by 3 unit and form graph of f(x).

[tex]f(x)= \log_2(x + 3)[/tex]

Transformation towards up,

f(x)→f(x)+a , the graph of f(x) is shifted upward by a unit.

Same as the graph g(x) is shifted upward by 2 unit and form graph of f(x).

[tex]f(x)= \log_2(x + 3)+2[/tex]

Therefore, The description of the transformation is 3 unit left and 2 unit up.
