The point (0, -1/2) on the graph of function f translates to g(x) = f(x + 1/2) + 2. The translation formula indicates that the new coordinates are determined by the shifts in the x and y directions. The correct new x-coordinate is -1/2, but the new y-coordinate needs adjustment. The final coordinates of the translated point are (-1/2, 3/2).

Q: The point (0,-1/2) is on the graph of f. If g is a translation of f so that g(x)=f(x+1/2) + 2, then what are the coordinates of the translated point?

I got the answer (-1/2, 2) but I'm not sure if that is the correct answer.
Thanks!

Re: PreCalc Functions Help

The translation:

$$f(x-h)+k$$

takes the point $(x,y)$ on $f$, and moves it to $(x+h,y+k)$.

You have the correct new $x$-coordinate, but not the correct new $y$-coordinate.
 
Here is a little puzzle from the book 100 Geometric Games by Pierre Berloquin. The side of a small square is one meter long and the side of a larger square one and a half meters long. One vertex of the large square is at the center of the small square. The side of the large square cuts two sides of the small square into one- third parts and two-thirds parts. What is the area where the squares overlap?
