<p>In the first edition of the Blue Book, section 2, problem 17, I am provided with y=f(x). It's graphed on the plane as a straight line that intercepts Y at 0,1, then slopes down to 1,0 on the X plane, then slopes upward. I am asked to find the graph of y=f(x+2). Considering that it is being increased on the X plane, I assumed the shape to me moved to the right (answer B). . . but the answer is C, where the shape moves back to the left! I can't figure this out, can someone help?</p>
<p>okay, your mistake is just an info mistake… when we add to the “x” in f(x) we move to the left… when we subtract from “x” in f(x) then we move to the right… since its asks which one is f(x+2) we have to move the graph to the left by two units as a result it is “C” and not “B”</p>
<p>Thanks, everyone! I think I understand. alliwantisthis, that website looks awesome! Wish I had heard about it earlier.</p>
