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
