Exponential Functions Graph Asymptote

An exponential function is graphed on the grid. Which function is best represented by the graph?

• The coordinates of the x-intercept are (0.25, 0).

• The coordinates of the y-intercept are (0, 8).

• The equation of the asymptote is x = 0.

• The graph includes the point (2, 1).
