Math Problem Statement
Based on the graph of the function g(x) provided, answer the following questions: (a) Find g(-4), g(-2), g(0), g(2), and g(4). (b) Determine the domain and range of g(x). (c) Identify the values of x for which g(x) = 3. (d) Estimate the values of x for which g(x) ≤ 0. (e) Calculate the net change in g(x) between x = -1 and x = 2.
Solution
Let’s solve the questions step by step based on the given graph of .
(a) , , , , and :
- : From the graph, when , .
- : When , .
- : When , .
- : When , .
- : When , .
(b) Domain and Range of :
- Domain: The graph extends horizontally from to , so .
- Range: The vertical extent of the graph is from to , so .
(c) Values of for which :
From the graph, at and .
(d) Values of for which :
From the graph, for:
- (from to , including endpoints).
(e) Net change in between and :
- At , .
- At , .
- Net change: .
Let me know if you would like a detailed explanation for any part or have further questions. Here are five follow-up questions you might find useful:
- How can you verify the domain and range from the graph?
- Why is the net change calculated as ?
- Can you determine if is a one-to-one function?
- How would you find where on this graph?
- What would the slope of the tangent line represent for at specific points?
Tip: Always observe whether a function is increasing or decreasing between points to better understand its behavior.
