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.

Answer 1

h(x) = f(x-13)

Think about it. All the x-values have to be 13 bigger to produce the same graph.

Answer 2

is that the answer

Answer 3

or is that an example

Answer 4

well, I guess it's both.
To translate in the positive direction (right or up) replace
x by x-h
y by y-k

Thus, given f(x), translate h units to the right and k units up,
h-k = f(x-h)
That is,
h(x) = f(x-h)+k
