Function f is an exponential function as shown in this table. By what factor does the output value increase as each input value increases by 1?

• 3

• 9

Answer explanation

Notice that in the table, the x values are increasing by 2, not 1. However, the question asks the growth factor as it increases by 1.

What are the end behaviors of f(x)?

• As x decreases without bound, the graph of f(x) increases without bound.

  As x increases without bound, the graph of f(x) increases without bound.

• As x decreases without bound, the graph of f(x) decreases without bound.

  As x increases without bound, the graph of f(x) decreases without bound.

• As x decreases without bound, the graph of f(x) approaches y = 2.

  As x increases without bound, the graph of f(x) increases without bound.

• As x decreases without bound, the graph of f(x) increases without bound.

  As x increases without bound, the graph of f(x) approaches y = 2.
