Question

use the graph of the function f shown to answer parts (a)-(n). (a) find f( - 21) and f( - 6). f( - 21)=□ f( - 6)=□

Explanation:

Step1: Locate x = - 21 on x - axis

Find the corresponding y - value on the graph. When x=-21, the point on the graph is (-21, - 8), so f(-21)=-8.

Step2: Locate x = - 6 on x - axis

Find the corresponding y - value on the graph. When x = - 6, the point on the graph is (-6,8), so f(-6)=8.

Answer:

f(-21)=-8
f(-6)=8
