Sketch the graph of a function with the given properties. You do not need to find a formula for the function.

p(0) = 2,lim x→0 p(x) = 0,lim x→2 p(x) does not exist, p(2)=lim x→2^+ p(x)=1

검증된 단계별 안내

Step 1: Start by plotting the point (0, 2) on the graph, as given by p(0) = 2. This indicates that the function passes through this point.

Step 2: Consider the limit as x approaches 0. The limit \( \lim_{x \to 0} p(x) = 0 \) suggests that as x gets very close to 0 from either side, the function value approaches 0. This implies a discontinuity at x = 0 since p(0) = 2.

Step 3: Analyze the behavior around x = 2. The limit \( \lim_{x \to 2} p(x) \) does not exist, indicating a discontinuity at x = 2. However, \( \lim_{x \to 2^+} p(x) = 1 \) tells us that as x approaches 2 from the right, the function value approaches 1.

Step 4: Plot the point (2, 1) on the graph to represent the right-hand limit at x = 2. Since the limit from the left does not exist, the function may have a jump or an asymptote at x = 2.

Step 5: Sketch the graph by connecting the points and considering the limits. The graph should approach 0 as x approaches 0 from either side, jump to 2 at x = 0, and then approach 1 from the right as x approaches 2.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Limits

Limits describe the behavior of a function as the input approaches a certain value. In this question, the limit as x approaches 0 indicates that the function approaches 0, while the limit as x approaches 2 does not exist, suggesting a discontinuity or a jump in the function's values at that point.

Continuity

A function is continuous at a point if the limit as x approaches that point equals the function's value at that point. In this case, p(0) = 2 while lim x→0 p(x) = 0 indicates that the function is not continuous at x = 0, as the limit does not match the function's value.

Piecewise Functions

Piecewise functions are defined by different expressions based on the input value. The properties given in the question suggest that the function p(x) may be piecewise, with different behaviors around x = 0 and x = 2, which is essential for sketching the graph accurately.
