x+4 moves it to the left by 4

x+4 would be a translation to the left

Irrespective of a

uh

ok let’s take a point (p, f(p))

and then see where this point goes on the graph f(x+4)

well see

x=1 goes to f(1+4) = 5 now

so (5, f(5)) actually goes to (1, f(5))

which means it got moved to the left

Btw this is sufficient for "show your work". Just give any reasoning
