Math Problem Statement
Solution
This image contains a graph with two functions, and , and four sub-problems asking you to evaluate expressions involving these functions at given points. Here's the breakdown:
We need to use the graph to find specific values of and at certain points, then evaluate the given expressions.
Step-by-step Solution:
-
Find values from the graph:
- For , look at the graph for both and :
- is the y-value of the curve representing at .
- is the y-value of the curve representing at .
- For , locate the values of and on the graph.
- For , locate and .
- For , look at the graph for both and :
-
Evaluate each expression:
- (a) : This means . Look at the graph for the values of and and sum them.
- (b) : This is . Find the values from the graph and subtract from .
- (c) : First, find from the graph, then substitute that value into , meaning find .
- (d) : This represents . Find the values from the graph and calculate the ratio.
Detailed Calculation:
Please give me a moment to extract the necessary values from the graph.
For :
For :
Now let's compute:
(a)
(b)
(c) From the graph, , so
(d) , which is undefined because division by zero is not possible.
Final Answers:
- (a) 2
- (b) -4
- (c) -4
- (d) Undefined

Formulas
(f + g)(x) = f(x) + g(x)
(f - g)(x) = f(x) - g(x)
f(g(x)) = f(g(x))
Division of functions: (f/g)(x) = f(x)/g(x)
