Math Problem Statement
Use the graph to determine a. the function's domain; b. the function's range; c. the x-intercepts, if any; d. the y-intercept, if any; and e. the missing function values, indicated by question marks, below. f left parenthesis negative 2 right parenthesisf(−2)equals=? f left parenthesis 2 right parenthesisf(2)equals=?
Solution
Let's analyze the provided graph and determine the requested information:
a. Domain of the function
The domain of a function is the set of all possible -values for which the function is defined. In this case, the curve extends from the left side of the graph at to the right side at , so the domain is:
b. Range of the function
The range is the set of all possible -values that the function attains. The highest point on the graph occurs just below , and the lowest point occurs at . Therefore, the range is:
(Note: The parenthesis for 3 indicates that the graph does not reach , only very close to it.)
c. -intercepts
The -intercepts are the points where the graph crosses the -axis. From the graph, we can see that the curve crosses the -axis at two points: and . Thus, the -intercepts are:
d. -intercept
The -intercept is the point where the graph crosses the -axis. The graph crosses the -axis at , so the -intercept is:
e. Missing function values
-
: To find , we look at the point on the graph where . From the graph, it seems the corresponding -value is around 2. Thus,
-
: Since is an -intercept, the function value at is zero:
Summary of Results:
- Domain:
- Range:
- -intercepts: and
- -intercept:
Would you like to go into more detail on any part? Here are some related questions:
- How can the function's symmetry be described based on the graph?
- What type of function might this be based on its shape (e.g., polynomial, quadratic)?
- How could the graph be transformed (shifted or scaled) to match a different function?
- What are the possible real-world applications of interpreting such functions?
- How does the domain and range change if the graph extends beyond or ?
Tip: When interpreting graphs, always check where the function intersects the axes, as this provides crucial information for solving equations involving roots and intercepts.
