linear transformation

Question

 The graph of f(x)=x was translated right 13 units to create the graph of h(x).

Write the equation of h(x) using function notation.

i got h(x)=x-13 and h(x) = f(x-13) but their both wrong

Answer 1

For example let f(x)=x or y=x

translate it to the right 13 units

you get:

y=x-13 =h(x) when x=13 y=0 Previously, x=0 meant y=0

0 to 13 for x is a clear shift to the right by 13

h(x)=x-13 has to be correct. Sometimes textbook answers are wrong, same with instructors answer keys
