which graph of f(x) satisfies these conditions? lim x→2 f(x)=−4 and lim x→2+ f(x)=0
Answer
Explanation:
Step1: Understand limit notation
$\lim_{x\rightarrow 2}f(x)= - 4$ means the overall limit as $x$ approaches 2 is -4. $\lim_{x\rightarrow 2^{+}}f(x)=0$ means the right - hand limit as $x$ approaches 2 (values of $x$ greater than 2) is 0.
Step2: Analyze graphs
For the right - hand limit as $x$ approaches 2, we look at the behavior of the graph for $x>2$. For the overall limit as $x$ approaches 2 to be -4, the graph should approach $y = - 4$ as $x$ gets close to 2 from both sides (even though the right - hand limit has a different value from the overall limit indicating a discontinuity). We check each graph for these behaviors.
Answer:
The graph that has the curve approaching $y = 0$ as $x$ approaches 2 from the right side ($x>2$) and the overall limit as $x$ approaches 2 being $y=-4$ is the correct one. Without specific labels on the graphs, we can't point out a particular letter - named graph, but the correct graph will have these limit characteristics.
