Question

question 18

which of the following describes the end behavior of a graph?

• the lowest point of the graph.
• the highest point of the graph.
• telling where the graph is increasing or decreasing.
• telling what the ends of the graph is doing.

question 19

what is the vertex of (f(x) = (x - 1)^2 - 4)?

• ((1, 4))
• ((4, 1))
• ((1, -4))
• ((-1, -4))

Explanation:

Define end behavior of a graph

Using the End Behavior knowledge point

$$ \text{End behavior describes the behavior of } f(x) \text{ as } x \to \infty \text{ and } x \to -\infty. $$

This corresponds to telling what the ends of the graph are doing.
