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 f(x)=x2f(x) = x^2 and g(x)=14(x+3)2+4g(x) = -\frac{1}{4}(x + 3)^2 + 4, follow these steps:

Step 1: Analyze f(x)=x2f(x) = x^2

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.
