1. 1.

   Ren changes f to g(x) = −f(x − 3) + 2 for a cloud's path in a game. The point (2, 4) is on f. Which point is on g? Write it like (7, -3).
2. 2.

   Zee changes f to g(x) = 3f(x − 1) + 7 for a rocket show. The point (4, -2) is on f. Which point is on g? Write it like (7, -3).
3. 3.

   Ari changes f to g(x) = −2f(x + 2) − 4 for a bike jump. The point (-3, -1) is on f. Which point is on g? Write it like (7, -3).
4. 4.

   (1, 3) | (-3, 3); (2, 5) | (-2, 5); (3, 7) | (-1, 7). Bo slides f(x) = 2x + 1, a train track, sideways for a game. The table shows three points before and after. If g(x) = f(x + c), what is c?
5. 5.

   (-1, 1) | (4, 1); (1, 1) | (6, 1); (2, 4) | (7, 4). Esme slides f(x) = x², a swing path, sideways for a game. The table shows three points before and after. If g(x) = f(x − c), what is c?
6. 6.

   (-2, 2) | (-9, 2); (1, 1) | (-6, 1); (3, 3) | (-4, 3). Jun slides f(x) = |x|, a valley on a map, sideways for a game. The table shows three points before and after. If g(x) = f(x + c), what is c?
