A scientist studies a radioactive isotope for several years. There are initially 100 radioactive isotopes that half every year.

Develop a model to represent the amount of radioactive isotope after x years.

What function best models this scenario?

• The coordinates of the x-intercept are (0.5, 0).

• The equation of the asymptote is x = 0.

• The graph includes the point (2.5, 1).

• The coordinates of the y-intercept are (0, 5).

What is the asymptote of y = 2^x - 3

• y = 0

• y = -3

• x = 0

• x = -3
