A new elementary school starts with a population of 600 students. Each year, the population increases by 35% per year. The school’s population can be modeled by

the function, p(x) = 600(1.35) , where x represents time in years and p(x) represents population of students.

Given the graph of p(x), which statement best describes the end behavior of the function?

• As x → ∞, p(x) → ∞

• As x → ∞, p(x) → –∞

• As x → 0, p(x) → ∞

• As x → 600, p(x) → 0

A graph of a rational function is shown. Describe the rational function.

• The function is increasing on the intervals (∞,- 3) U (- 3, 2) U (2, ∞) and has a horizontal asymptote at y=0.

• The function has vertical asymptotes at x = 0 and x = 2.

• The function is even because it reflects evenly across the y-axis and has a removable discontinuity at x=5.

• The function is the inverse of y=x.

Which statement best describes and justifies the symmetry of the graph shown?

• The graph is even because it is symmetric with respect to the x-axis.

• The graph is odd because it is symmetric with respect to the origin.

• The graph is both even and odd because it is symmetric to both the x- and y-axis.

• The graph is neither even nor odd because it has no symmetry with respect to either

  axis.
