Question

How do you describe the translation from the graph `y= 2(x-15)^2+3` to the graph of `y=2(x-11)^2+3`?

Answer 1

The graph is shifted `4` units left

Explanation:

To make the function `y=2(x-15)^2+3` the same as `y=2(x-11)^2+3`, you have to add `color(red)4` inside the bracket

`2(x-15color(red)(+4))^2+3`

This added `color(red)4` shifts the graph `color(red)4` units left
