Math Problem Statement

Which values of x appear to be solutions to f(x) = g(x)? Select all that apply.

Solution

To solve the question, we need to find the xx-values where the two functions, f(x)f(x) and g(x)g(x), intersect. These are the points where f(x)=g(x)f(x) = g(x).

Analysis of the graph:

  • The function f(x)f(x) is the green curve.
  • The function g(x)g(x) is the blue straight line.

The intersections occur at the following approximate xx-values:

  1. x=8x = -8
  2. x=4x = -4
  3. x=4x = 4

These are the xx-values that satisfy f(x)=g(x)f(x) = g(x). Therefore, the solutions are 8-8, 4-4, and 44.

Let me know if you'd like a more detailed explanation or have questions!


Here are five related questions for further exploration:

  1. How do we algebraically find the solutions to f(x)=g(x)f(x) = g(x) if equations for f(x)f(x) and g(x)g(x) are provided?
  2. What happens if f(x)f(x) and g(x)g(x) do not intersect at any point?
  3. Can a function f(x)f(x) intersect g(x)g(x) more than three times?
  4. How do the slopes of the functions affect the number of intersections?
  5. How would the solutions change if the graph of f(x)f(x) shifted upwards or downwards?

Tip: Always check graph scales carefully when identifying intersection points to avoid errors.
