PCHA 2021-22 / Dr. Kessner

Graph each of the functions below. Then determine the following properties of the function:

  • domain and range
  • discontinuities (removable, jump, infinite)
  • intervals of increasing/decreasing
  • boundedness (above/below)
  • local/global extrema
  • odd/even symmetry
  • asymptotes (with limits)
  • end behavior (with limits)

1. $\sin(x), \cos(x), \tan(x), \csc(x), \sec(x), \cot(x)$.

2. $x, x^2, x^3, x^4$

3. $|x|, \dfrac{|x|}{x}$

4. $\sqrt{x}, \sqrt[3]{x}$

5. $\dfrac{1}{x}$

6. $2^x, 10^x$
