Math Problem Statement

Given the quadratic function f(x) = -0.5x^2 + 1, fill in the details such as domain, range, intercepts, and increasing/decreasing intervals.

Solution

The image you uploaded contains a function f(x)=0.5x2+1f(x) = -0.5x^2 + 1 and a partially filled-in chart with graphing details, such as domain, range, intercepts, and increasing/decreasing intervals. Below, I'll walk through the problem step-by-step, providing explanations for each component of the function and the requested details.

1. Parent Function:

The given function is a quadratic function f(x)=0.5x2+1f(x) = -0.5x^2 + 1, so its parent function is: f(x)=x2f(x) = x^2 This is a standard parabola that opens upward, with the vertex at (0,0)(0, 0).

2. Transformations:

There are two transformations applied to the parent function:

  • Vertical Compression: The coefficient 0.5-0.5 compresses the graph vertically by a factor of 0.5 and reflects it over the x-axis.
  • Vertical Shift: The constant term +1+1 shifts the graph upward by 1 unit.

3. Graphing:

The graph is a downward-facing parabola due to the negative coefficient. The vertex of the parabola is at (0,1)(0, 1), which comes from the transformation of the parent function.

4. Domain:

The domain of a quadratic function is all real numbers: [ \text
