On this coordinate plane, point A is translated into point A'. Which functions give the two translations?

a. f (x) = x - 5 and g (y) = y - 2
b. f (x) = x + 6 and g (y) = y + 2
c. f (x) = x + 5 and g (y) = y + 2
d. f (x) = x + 2 and g (y) = y + 5

To determine which functions correspond to the translations from point A to point A', we need to analyze the translations in terms of how the coordinates change.

In general, a function of the form \( f(x) = x + a \) translates the x-coordinate by \( a \) units, where a positive \( a \) moves the point to the right and a negative \( a \) moves it to the left. For the y-coordinate, a function of the form \( g(y) = y + b \) translates the y-coordinate by \( b \) units, where a positive \( b \) moves the point up and a negative \( b \) moves it down.

Let's break down the given options:

a. \( f(x) = x - 5 \) and \( g(y) = y - 2 \) corresponds to translating left by 5 units and down by 2 units.

b. \( f(x) = x + 6 \) and \( g(y) = y + 2 \) corresponds to translating right by 6 units and up by 2 units.

c. \( f(x) = x + 5 \) and \( g(y) = y + 2 \) corresponds to translating right by 5 units and up by 2 units.

d. \( f(x) = x + 2 \) and \( g(y) = y + 5 \) corresponds to translating right by 2 units and up by 5 units.

To find the correct translations, we need to know the specific coordinates of point A and point A'. If you can provide those coordinates, I can help identify which translation (a, b, c, or d) relates to that transformation.
