Math Problem Statement
Solution
Let's analyze the graph and solve the given problems:
From the image of the graph and the question:
- The graph shows a V-shaped function which seems to be a piecewise linear function. Based on the visual information, let's tackle each part.
a. Domain: The domain represents all the possible -values that the function can take. Since the graph extends infinitely in both directions along the x-axis, the domain appears to be all real numbers.
Domain:
b. Range: The range represents all the possible -values that the function can output. The graph has a minimum point at , and the function increases from this point. Thus, the range will be all values greater than or equal to .
Range:
c. X-intercepts: The x-intercepts are the points where the function crosses the x-axis (i.e., where ). Based on the graph, the function crosses the x-axis at and .
X-intercepts:
d. Y-intercept: The y-intercept is the point where the function crosses the y-axis (i.e., where ). From the graph, this happens at .
Y-intercept:
e. Function values:
- : From the graph, when , the corresponding -value is .
- : When , the corresponding -value is .
Summary of the answers:

- c. X-intercepts:
- d. Y-intercept:
- e. Function values: ,
