Math Problem Statement

The graph of the function g(x) = -x^4 + 6x^2 - 8 is shown. Which are the solutions of g(x) = -2?

Solution

The question asks for the solutions of the function g(x)=x4+6x28g(x) = -x^4 + 6x^2 - 8 at certain points, based on the provided graph.

Steps to Solve:

  1. Identify where g(x)=2g(x) = -2 on the graph:

    • We need to find the x-values where the function reaches the value of -2 on the y-axis (i.e., g(x)=2g(x) = -2).
    • This corresponds to the points where the horizontal line y=2y = -2 intersects the curve.
  2. Interpreting the Graph:

    • From the graph, the curve intersects y=2y = -2 at two points:
      • One near x = -2.
      • One near x = 2.
  3. Checking the Options:

    • From the possible choices:
      • The correct pair of solutions appears to be x=2x = -2 and x=2x = 2.

Answer:

  • The correct option is: x=2x = -2 and x=2x = 2.
