Solution

To find f(7)f(7) from a graph, follow these steps:

  1. Locate x=7x = 7 on the xx-axis.
  2. Move vertically until you intersect the graph of y=f(x)y = f(x).
  3. From this intersection point, read the corresponding yy-value. This yy-value is f(7)f(7).

If you have access to the graph, you can confirm the specific yy-value at x=7x = 7. Let me know if you'd like more detailed help based on the graph you have!

Would you like further assistance or examples? Here are some related questions to deepen understanding:

  1. How do we determine if a function is increasing or decreasing from a graph?
  2. What is the process for finding f(2)f(-2) given a graph?
  3. How can we estimate values between points on a graph?
  4. How do we determine the maximum or minimum values of a function from a graph?
  5. What is the meaning of f(x)=0f(x) = 0 in terms of the graph?

Tip: When reading values from a graph, always align the xx-value with the graph carefully to avoid mistakes!
