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)= 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= (use a comma to separate answers as needed.)

Explanation:

Step1: Locate x - values on graph

To find the values of \(x\) for which \(f(x)=0\), we look at the points where the graph of the function \(y = f(x)\) intersects the \(x\) - axis.

Step2: Identify intersection points

From the graph, the function \(y = f(x)\) intersects the \(x\) - axis at \(x=-18\), \(x = 12\).

Answer:

\(-18,12\)
