Question

question 16, 3.2.11 part 2 of 14 use the graph of the function f shown to answer parts (a)-(n) (a) find f(-21) and f(-6). f(-21)= - 8 f(-6)=8 (b) find f(18) and f(0). f(18)= f(0)=

Explanation:

Step1: Locate x - value on x - axis

To find \(f(18)\), locate \(x = 18\) on the x - axis of the graph. Then, find the corresponding y - value on the graph of the function \(y=f(x)\).

Step2: Read y - value

From the graph, when \(x = 18\), the y - value (the value of the function) is \(8\).

Step3: Locate x - value for \(f(0)\)

Locate \(x = 0\) on the x - axis of the graph. Then, find the corresponding y - value on the graph of the function \(y = f(x)\).

Step4: Read y - value for \(f(0)\)

From the graph, when \(x=0\), the y - value (the value of the function) is \(- 8\).

Answer:

\(f(18)=8\)
\(f(0)= - 8\)
