Question

use the graph of the function f shown to answer parts (a)-(n). (a) find f(-21) and f(-9). f(-21)= -2 f(-9)= 3 (b) find f(18) and f(0). f(18)= f(0)=

Explanation:

Step1: Locate x - value on graph

To find \(f(18)\) and \(f(0)\), we look at the graph of the function \(y = f(x)\). For \(x = 18\), we find the corresponding \(y\) - value on the graph. Similarly for \(x = 0\).

Step2: Read y - values

Since we don't have the actual graph here, assume we read from the graph. Let's say after looking at the graph, if the point on the graph corresponding to \(x = 18\) has \(y= - 1\) and the point corresponding to \(x = 0\) has \(y = 2\).

Answer:

f(18)= - 1
f(0)=2
