Math Problem Statement

Find the value of h(2) from the given graph below.

Solution

From the graph provided, we need to determine the value of h(2)h(2).

Step-by-step solution:

  1. Locate x=2x = 2 on the horizontal axis.
  2. Trace vertically at x=2x = 2 to find the corresponding value of h(x)h(x) (on the vertical axis).
  3. At x=2x = 2, the graph shows an open circle at h(x)=1h(x) = 1, which indicates that h(2)h(2) is not defined at 1.
  4. However, moving further, the graph dips to h(x)=3h(x) = -3 at x=2x = 2, represented by a filled point. This indicates that h(2)=3h(2) = -3.

Final Answer:

h(2)=3h(2) = -3

Would you like more details or explanations? Here are some related questions to deepen understanding:

  1. What does an open circle on a graph represent in terms of function values?
  2. How can you identify the domain of a piecewise function from its graph?
  3. Why is the filled point at x=2x = 2 the valid value for h(2)h(2)?
  4. How would the graph change if h(2)h(2) were instead defined at h(x)=1h(x) = 1?
  5. What is the importance of distinguishing open and closed circles in evaluating functions?

Tip: Always double-check for open and closed points when interpreting graphs of piecewise functions to avoid errors in determining function values.
