Use a graphing utility to graph the function. Use the graph to determine the behavior of the function as
x → c.
f(x) = sec(x)

Answer:
Step-by-step explanation:
Moving toward the left, the graph of f(x) goes to -∞ as x nears π/2. It goes to +∞ as x nears -π/2.
Moving to the right, the graph of f(x) goes to -∞ as x nears -π/2. It goes to +∞ as x nears π/2.
