The exponential function f(x) has a horizontal asymptote at y = 3. What is the end behavior of f(x)?

• As x decreases, f(x) approaches, but never reaches, 0. As x increases, f(x) increases.

• As x decreases, f(x) approaches, but never reaches, 3. As x increases, f(x) increases.

• As x decreases, f(x) approaches, but never reaches, 3. As x increases, f(x) decreases.

• As x decreases, f(x) decreases. As x increases, f(x) approaches, but never reaches, 3.

Tina was observing the changing heights of a ball as it bounced over time. She graphed the function on this coordinate grid to show f(x), the height of the dropped ball, in feet, after its xth bounce.

Find f(3). Explain what this value represents in the given context.

1. Tina was observing the changing heights of a ball as it bounced over time. She graphed the function on this coordinate grid to show f(x), the height of the dropped ball, in feet, after its xth bounce.

Tina said that a possible range for the given function is y > 0. Do you agree or disagree? If you agree, explain why the range is correct. If you disagree, what values should be the range for the given scenario?
