Math Problem Statement

The graph of y = f(x) is shown below. Find all values of x where f(x) = 0.

Solution

Based on the graph of y=f(x)y = f(x) shown, we are asked to find all values of xx where f(x)=0f(x) = 0.

From the graph, f(x)=0f(x) = 0 when the curve intersects the x-axis. Let's observe the points where the curve crosses the x-axis.

The graph crosses the x-axis at three points:

  1. x=7x = -7
  2. x=3x = -3
  3. x=3x = 3

Therefore, the solutions to f(x)=0f(x) = 0 are:

x=7,3,3x = -7, \, -3, \, 3

Would you like a more detailed explanation or clarification on any of these steps? Here are a few related questions you might find interesting:

  1. How can we determine the number of real roots of a function from its graph?
  2. What is the significance of the x-axis intercepts of a function in relation to its zeros?
  3. How can we find the exact x-values where a polynomial intersects the x-axis using algebra?
  4. How would the graph of a function change if one of the roots was a double root?
  5. How can the behavior of a function near its intercepts help determine the nature of its roots?

Tip: When solving for the roots or zeros of a function, it’s helpful to first identify where the graph crosses the x-axis. Each crossing point represents a root of the function.
