Hello, I'm reviewing graph transformation and I stumbled on this question. I'm looking for why my method is incorrect.
Question: If [imath]f(x) =3x+4[/imath], then state the transformation for [imath]f(x+3)[/imath].
The answer is obvious it shifted to the left 3, however, I did it a bit differently.
If [imath]f(x) =3x+4[/imath], then [imath]f(x+3)=3(x+3)+4= 3x+4+9=f(x)+9[/imath]. So I said shifted up 9.
Why is this wrong?
