Math Problem Statement

Find the value of f(7).

Solution

To find the value of f(7)f(7), we need to determine the y-coordinate of the function y=f(x)y = f(x) at x=7x = 7. From the graph:

  1. Locate x=7x = 7 on the x-axis.
  2. From x=7x = 7, move vertically to where the graph intersects this line. The y-coordinate at that intersection represents f(7)f(7).

By looking at the graph, at x=7x = 7, the function intersects the y-axis at y=8y = -8.

Therefore, the value of f(7)=8f(7) = -8.

  1. What is the value of f(0)f(0) from the graph?
  2. What is the minimum value of the function and where does it occur?
  3. How would you determine f(9)f(9) from the graph?
  4. Can you estimate the x-values for which f(x)=0f(x) = 0?
  5. What are the maximum and minimum values of f(x)f(x) within the range shown?

Tip:

Always double-check function values by clearly tracing the graph at the specified x-value to the corresponding y-value.
