Q17. From the graph of a function, list all input values where .

Background

Topic: Reading function values from a graph

This question tests your ability to interpret a graph and identify the input values (x-values) where the function output (y-value) equals a specific number.

Key Terms:

• Function: A relation that assigns exactly one output value for each input value.

• Input value (x): The value you substitute into the function.

• Output value (f(x)): The value the function returns for a given input.

Step-by-Step Guidance

1. Look at the graph and identify the horizontal line where . This is the line .

2. Find the points where the graph of the function intersects this horizontal line. These intersection points represent the input values where .

3. For each intersection, read the corresponding x-value from the graph. These are the values you are looking for.

4. Write down the x-values where the graph meets . These are the input values where .
