Math Problem Statement
1. The function, g(x) is shown on the graph.
a) Find g(2)
b) Find g(-3)
c) Find the value of g(2) + g(1)
d) Find the value(s) of x when g(x) = 0
e) Find the value(s) of x when g(x) = -2
f) State the domain of the function
g) State the range of the function.
Solution
Let's analyze the graph and solve the questions one by one:
-
The function is shown on the graph.
a) Find :
- Looking at on the graph, the value of is approximately 6.
b) Find :
- At , the value of is 0 (as the point crosses the x-axis at this point).
c) Find the value of :
- We already found that .
- For , looking at on the graph, the value is 7.
- So, .
d) Find the value(s) of when :
- where the graph crosses the x-axis.
- This happens at and .
- So, and .
e) Find the value(s) of when :
- Look for where the graph hits on the y-axis.
- This happens at and .
- So, and .
f) State the domain of the function:
- The domain is the set of all possible -values.
- Based on the graph, the function is defined for values between and .
- So, the domain is .
g) State the range of the function:
- The range is the set of all possible -values.
- From the graph, the function takes values between and .
- So, the range is .
Would you like further details on any part of this? Here are some related questions for deeper understanding:
- How can you determine the domain and range of a function from a graph?
- What are the important features of a graph (e.g., intercepts, increasing/decreasing intervals)?
- How would you express a function that passes through certain points as an equation?
- What happens if the graph is shifted up or down? How does that affect the range?
- Can you find the inverse of this function based on its graph?
Tip: Always check the x-intercepts and y-intercepts of a graph to easily identify when the function equals 0 and the domain/range limits.
