Which phrase best describes the translation from the graph [tex]$y=6x^2$[/tex] to the graph of [tex]$y=6(x+1)^2$[/tex]?

A. 6 units left
B. 6 units right
C. 1 unit left
D. 1 unit right



Answer :

To understand the translation from the graph of [tex]\( y = 6x^2 \)[/tex] to the graph of [tex]\( y = 6(x + 1)^2 \)[/tex], let's analyze the transformation step-by-step.

1. Identify the original function: The original quadratic function given is [tex]\( y = 6x^2 \)[/tex]. This is a parabola centered at the origin [tex]\((0, 0)\)[/tex] and opens upwards.

2. Understand the transformation: The transformed function is [tex]\( y = 6(x + 1)^2 \)[/tex]. To see how this changes the graph, we need to analyze the [tex]\( (x + 1)^2 \)[/tex] term.

3. Effect of the [tex]\( (x + 1)^2 \)[/tex] term:
- In the function [tex]\( y = 6(x + 1)^2 \)[/tex], the [tex]\( +1 \)[/tex] inside the square term means that the graph of the function is moved horizontally.
- Specifically, the [tex]\( (x + 1) \)[/tex] means every [tex]\( x \)[/tex] value is replaced by [tex]\( x + 1 \)[/tex], which effectively shifts the graph to the left by 1 unit.

4. Visualization:
- For the original equation [tex]\( y = 6x^2 \)[/tex], the vertex is at [tex]\( (0, 0) \)[/tex].
- For the transformed equation [tex]\( y = 6(x + 1)^2 \)[/tex], the new vertex is at [tex]\( (-1, 0) \)[/tex].

Therefore, the correct phrase that best describes the translation is:

1 unit left

This matches our detailed step-by-step analysis.
