Step 1: To determine the x-intercepts, observe where the orange curve crosses the x-axis. The x-intercepts are the points where the y-value is zero.
Step 2: To determine the y-intercepts, observe where the orange curve crosses the y-axis. The y-intercepts are the points where the x-value is zero.
Step 3: From the graph, note that the tick marks along the axes represent one unit each. Carefully count the units to identify the exact coordinates of the intercepts.
Step 4: For the x-intercepts, locate the points where the curve intersects the x-axis. These points will have coordinates of the form (x, 0).
Step 5: For the y-intercepts, locate the point where the curve intersects the y-axis. This point will have coordinates of the form (0, y).

주요 개념

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

X-Intercepts

X-intercepts are the points where a graph crosses the x-axis. At these points, the value of y is zero. To find the x-intercepts, one can set the equation of the graph equal to zero and solve for x. In the context of the provided graph, identifying these points helps in understanding the behavior of the function at specific values of x.

Y-Intercepts

Y-intercepts are the points where a graph crosses the y-axis, where the value of x is zero. To determine the y-intercept, one can substitute x = 0 into the equation of the graph and solve for y. This point is crucial as it indicates the value of the function when no input from the x-axis is present, providing insight into the function's initial value.

Graph Interpretation

Graph interpretation involves analyzing the visual representation of a function to extract meaningful information about its behavior. This includes identifying intercepts, understanding the shape of the curve, and recognizing trends such as increasing or decreasing intervals. Effective graph interpretation is essential for solving problems related to functions and their properties, as it allows for a deeper understanding of the relationship between x and y.
