Question

How does the graph of a function g(x)=x+4 differ from the parent linear function f(x)=x

Answer 1

g(x) = f(x) + n - shift a graph of f(x) n units up

g(x) = f(x) - n - shift a graph of f(x) n units down

g(x) = f(x - n) - shift a graph of f(x) n units right

g(x) = f(x + n) - shift a graph of f(x) n units left

-----------------------------------------------------------------------------

f(x) = x

g(x) = x + 4 = f(x) + 4

Answer: Shift a graph of f(x) n units up.
