Which of the graphs best suits the following equation?
[tex]y = 6^{-x}[/tex]

Graph 1 - The x y-coordinate plane is given. The curve enters the window at the approximate point (−1.2, 8.6), goes down and right becoming less steep, crosses the y-axis at y = 1, and exits the window just above the x-axis.

Graph 2 - The x y-coordinate plane is given. The curve enters the window at the approximate point (−1.2, −8.6), goes up and right becoming less steep, crosses the y-axis at y = −1, and exits the window just below the x-axis.

Graph 3 - The x y-coordinate plane is given. The curve enters the window just above the x-axis, goes up and right, crosses the y-axis at y = 1, and exits the window at the approximate point (1.2, 8.6).

Graph 4 - The x y-coordinate plane is given. The curve enters the window just below the x-axis, goes down and right, crosses the y-axis at y = −1, and exits the window at the approximate point (1.2, −8.6).
