A partial graph of an exponential function is shown in the graph. What are the domain and range of this graph?

• Domain: 0 < y < 8

  Range: x > -7

• Domain: x ≥ -7

  Range: 0 < y ≤ 8

• Domain: x > -7

  Range: 0 < y < 8

• Domain: 0 ≤ y ≤ 8

  Range: x ≥ -7

The graph of an exponential function is shown on the grid. Based on the graph, which statement about the function is true?

• The range is the set of all real numbers less than 0.

• The domain is the set of all real numbers greater than -4.

• The range is the set of all real numbers greater than 0.

• The domain is the set of all real numbers less than -4.

The population of Center City is modeled by exponential function f, where x is the number of years after the year 2015. The graph of f is shown on the grid.

Which inequality best represents the range of f in this situation?

• x ≥ 0

• 0 ≤ x ≤ 110

• 250,000 ≤ y ≤ 1,000,000

Which statement is true?

• The range is the set of all real numbers less than 0.

• The domain is the set of all real numbers greater than -4.

• The domain is the set of all real numbers less than -4.

• The range is the set of all real numbers greater than 0.
