Question

Ella draws a hexagon on the coordinate grid and shifts it 7 units to the left. Use a function to show the translation. What function does Ella write?

Answer 1

She should shift each x-coordinate left 7, leaving y the same. For points (x,y) the translation is

T(x,y) = (x − 7, y).

(For example, (3,2) → (−4,2).)
