Question

question 16, 3.2.11 part 10 of 14 use the graph of the function f shown to answer parts (a)-(n). (f) for what values of x is f(x)>0? -18<x<-3,12<x≤18 (type a compound inequality. use a comma to separate answers as needed.) (g) what is the domain of f? the domain of f is {x| -21≤x≤18}. (type a compound inequality.) (h) what is the range of f? the range of f is {y| -8≤y≤12}. (type a compound inequality.) (i) what are the x - intercept(s)? x = -18,-3,12 (type an integer or a simplified fraction. use a comma to separate answers as needed.) (j) what are the y - intercept(s)? y = (type an integer or a simplified fraction. use a comma to separate answers as needed.)

Explanation:

Step1: Identify y - intercept definition

The y - intercept is the value of y when x = 0.

Step2: Locate x = 0 on graph

Looking at the graph, when x = 0, y=-4.

Answer:

y = - 4
