Solution by Steps
step 1
To find the limit of g(x)g(x) as xx approaches negative infinity, we observe the behavior of the graph on the left side. The graph of g(x)g(x) starts horizontally at approximately y=4y = 4 and then approaches negative infinity as it nears the dashed line at x=3x = -3. Therefore, limxg(x)=4\lim_{x \rightarrow -\infty} g(x) = 4
step 2
To find the limit of g(x)g(x) as xx approaches positive infinity, we observe the behavior of the graph on the right side. The graph of g(x)g(x) comes from positive infinity along the dashed line at x=3x = -3 and then becomes mostly horizontal near y=1y = 1. Therefore, limxg(x)=1\lim_{x \rightarrow \infty} g(x) = 1
Answer
limxg(x)=4\lim_{x \rightarrow -\infty} g(x) = 4 and limxg(x)=1\lim_{x \rightarrow \infty} g(x) = 1
Key Concept
Limits at infinity
Explanation
The limits at infinity describe the behavior of the function as xx approaches very large positive or negative values. In this case, the graph shows horizontal asymptotes indicating the function's values as xx goes to negative and positive infinity.
