Math Problem Statement

The graph of f(x) = 2|x| is given. Write the equation of a function g(x) which would shift the graph of f(x) right 5 units.

Solution

To solve this problem, we need to shift the graph of f(x)=2xf(x) = 2|x| right by 5 units.

When shifting a function f(x)f(x) horizontally:

  • To shift right by cc units, replace xx with xcx - c in the function.
  • Therefore, the equation becomes: g(x)=2x5g(x) = 2|x - 5|

Thus, the function g(x)g(x) that shifts f(x)f(x) to the right by 5 units is: g(x)=2x5g(x) = 2|x - 5|

Let me know if you’d like me to provide additional explanations or visualizations of this transformation.

Tip:

To confirm your graph transformations, try substituting key points from the original graph into the transformed equation to check if the new graph shifts correctly.
