Question 563796
Let's look at the graphs for {{{highlight(f(x) = x)}}} and {{{highlight_green(g(x) = x+5)}}}:
{{{graph(400,400,-10,5,-5,10, x,x+5)}}}
You can see that the graph of {{{highlight_green(g(x) = x+5)}}} is just the graph of {{{highlight(f(x) = x)}}} only shifted up 5 spaces.
That is, for every x-value on the graph of {{{highlight(f(x) = x)}}}, the graph of {{{highlight_green(g(x) = x+5)}}} has 5 added to it.
