Math Problem Statement
Sketch the graph of the pair of functions. Use a dashed line for g(x).
f(x) = x2 , g(x) = - (1/4)(x + 3)2 + 4
Solution
To sketch the graphs of the functions and , follow these steps:
Step 1: Analyze
This is a standard parabola that opens upwards with the vertex at the origin (0,0). Key features include:
- Vertex: (0, 0)
- Axis of symmetry: The y-axis (x = 0)
- Shape: Symmetric and upwards, passing through points like (-1, 1), (1, 1), (-2, 4), (2, 4), etc.
