Question

use the graph of the function f shown to answer parts (a)-(n). f(18)=2 f(0)= - 1 (c) is f(6) positive or negative? negative positive (d) is f(-21) positive or negative? negative positive (e) for what value(s) of x is f(x)=0? x=-18,-3,12 (use a comma to separate answers as needed.) (f) for what values of x is f(x)>0? (type a compound inequality. use a comma to separate answers as needed.)

Explanation:

Step1: Analyze the graph

Observe the graph of \(y = f(x)\) to find where \(y>0\).

Step2: Identify intervals

The function \(y = f(x)\) is above the \(x -\)axis (where \(y>0\)) when \(- 18

Answer:

\(-18 < x < - 3,12 < x\leq18\)
