It appears that you are referring to a specific graph of a function \( f(x) \) that is not visible in the text. To accurately identify the key features of the graph, I would need either a description of the graph or the graph itself.
However, I can explain how to determine the key features of a quadratic function, as they often appear in graph problems. Here’s a brief overview of how to find the vertex, axis of symmetry, y-intercept, and x-intercepts of a quadratic graph in general:
Part A: Key Features of the Graph
-
Vertex:
- For a quadratic function in standard form \( f(x) = ax^2 + bx + c \), the vertex can be found using the formula: \[ x = -\frac{b}{2a} \]
- Once you find \( x \), substitute it back into the function to find \( f(x) \), which gives the vertex coordinates \((x, f(x))\).
-
Axis of Symmetry:
- The axis of symmetry is the vertical line that passes through the vertex, which can be represented as: \[ x = -\frac{b}{2a} \]
-
y-intercept:
- The y-intercept occurs where \( x = 0 \). To find it, calculate \( f(0) \). The coordinates of the y-intercept will be \((0, f(0))\).
-
x-intercepts:
- The x-intercepts can be found by solving the equation \( f(x) = 0 \). Graphically, these are the points where the graph crosses the x-axis, and their coordinates will be \((x_1, 0)\) and \((x_2, 0)\).
Part B:
If you have specific elements of the graph or a description, please provide that information, and I can assist you further with calculating the values mentioned.
