1-87.

Review the directions for writing approach statements in the Math Notes box in Lesson 1.2.3. Then write a complete set of approach statements for $y = 3^{−x} + 1$.

A complete approach statement should include information about interesting parts of the graph, for example: holes, vertical asymptotes, roots, and what happens as $x$ approaches $+∞$ and $−∞$.

As $x → −∞, y →$ ___________

There is no horizontal asymptote to the left.

As $x → ∞, y →$ ___________

This is the horizontal asymptote to the right.
