Chapter 5 - Trigonometric Functions - Section 5.5 Graphs of the Tangent, Cotangent, Cosecant, and Secant Functions - 5.5 Assess Your Understanding - Page 442: 29

Answer

See graph, domain $\{x| x\ne 2k\pi+\pi\}$ (k is an integer), range $\{y|y\le-4\ or\ y\ge4\}$.

Work Step by Step

1. See graph for $y=4sec(\frac{1}{2}x)$. 2. We can identify the domain $\{x| x\ne 2k\pi+\pi\}$ (k is an integer), range $\{y|y\le-4\ or\ y\ge4\}$.
