Question

use the graph of the function f shown to answer parts (a)-(n). f(18)=8 f(0)= - 4 (c) is f(6) positive or negative? positive negative (d) is f(-21) positive or negative? positive negative (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 f(x)>0 condition

We need to find where the graph of the function is above the x - axis.

Step2: Identify intervals from graph

From the graph, we see that the function is above the x - axis when - 18 < x < - 3 and 12 < x < 18.

Answer:

• 18 < x < - 3,12 < x < 18
