Solution by Steps
step 1
To determine the domain of the function f(x)f(x), we need to identify the set of all xx-values for which the function is defined. From the graph, we observe that the function starts at x=4x = -4 and ends at x=6x = 6
step 2
Therefore, the domain of f(x)f(x) is the interval [4,6][-4, 6]
step 3
To determine the range of the function f(x)f(x), we need to identify the set of all yy-values that the function takes. From the graph, we observe that the minimum yy-value is 22 and the maximum yy-value is 44
step 4
Therefore, the range of f(x)f(x) is the interval [2,4][2, 4]
Answer
Domain: [4,6][-4, 6]
Range: [2,4][2, 4]
Key Concept
Domain and Range of a Piecewise Function
Explanation
The domain of a function is the set of all possible input values (x-values) for which the function is defined, while the range is the set of all possible output values (y-values) that the function can take.
