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 = 18 on graph

Find the y - value at x = 18 on the function graph.

Step2: Locate x = 0 on graph

Find the y - value at x = 0 on the function graph.

Answer:

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