enter +infinity or -infinity. if the limit does not exist, enter dne. a) lim_{x-> - 9}f(x) b) lim_{x-> - 3}f(x)
Answer
Explanation:
Step1: Analyze limit as x approaches - 9
Examine the graph near x = - 9. As x approaches - 9 from both the left - hand side and the right - hand side, the function values approach the same y - value.
Step2: Determine the limit value
By observing the graph, we can see that as x gets closer and closer to - 9, f(x) approaches - 4.
Step3: Analyze limit as x approaches - 3
Examine the graph near x=-3. As x approaches - 3 from the left - hand side and the right - hand side, the function values approach the same y - value.
Step4: Determine the limit value
By observing the graph, as x gets closer and closer to - 3, f(x) approaches 4.
Answer:
a) - 4 b) 4
