What is the effect on the graph of the parent function f(x) = x when f(x) is replaced with f(x - 7)?

Question

what is the effect

Answer 1

The graph is translated 7 units to the right.  Here are the rules to remember:

 

For POSITIVE x₀,

 

f(x - x₀) is translated x₀ units to the right

f(x + x₀) is translated x₀ units to the left
