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!

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.
 
I have been insisting to my statistics students that for probabilities, the rule is the number of significant figures is the number of digits past the leading zeros or leading nines. For example to give 4 significant figures for a probability: 0.000001234 and 0.99999991234 are the correct number of decimal places. That way the complementary probability can also be given to the same significant figures ( 0.999998766 and 0.00000008766 respectively). More generally if you have a value that...
