Which is the equation of an ellipse with directrices at x = ±4 and foci at (2, 0) and (−2, 0)?

If you apply the changes below to the absolute value parent function, f(x)=\x\, which of these is the equation of the new function? shift 2 units to the left shift 3 units down a. g(x)=\x-3\-2 b. g(x)= \x-2\-3 c. g(x)= \x+3\-2 d. g(x)= \x+2\-3

Can someone check if i did this correct. it’s number 4 if you’re wondering.
