Use the image to answer the question.

Two side-by-side shaded ovals labeled x and y each display a list of values. Four arrows point from the values in the left oval, x, to the values in the right oval, y.

Which equation describes the function shown in the mapping diagram?

f(x)=12x−8
f left parenthesis x right parenthesis equals Start Fraction 1 over 2 End Fraction x minus 8

f(y)=12x−8
f left parenthesis y right parenthesis equals Start Fraction 1 over 2 End Fraction x minus 8

f(x)=8x−12
f left parenthesis x right parenthesis equals 8 x minus Start Fraction 1 over 2 End Fraction

f(y)=8x−12
f left parenthesis y right parenthesis equals 8 x minus Start Fraction 1 over 2 End Fraction

To determine which equation describes the function shown in the mapping diagram, we would need to analyze the relationships between the values in the ovals x and y based on the arrows connecting them.

Since I don't have the image to reference, I’ll guide you on how to approach such problems:

  1. Identify the Input and Output: The left oval represents the input (function domain) values of x, while the right oval represents the output (function range) values of y. Check how values from x relate to y.

  2. Look at the Mapping: Each arrow indicates a transformation from an input value x to an output value y. Take note of the operations being performed (additions, subtractions, multiplications, or divisions).

  3. Construct the Function: Based on the transformation observed, you should be able to express y in terms of x. If y is being derived from x by linear operations, you can write a function like \( f(x) \).

Given the options provided, check if they represent direct relationships (like \( y = mx + b \) where \( m \) is the slope and \( b \) is the y-intercept).

  1. Evaluate the Choices: Pick the option that correctly describes the transformation you've identified.

If for example arrows from x to y suggest a transformation like \( y = \frac{1}{2}x - 8 \), then the correct answer would be:

  • \( f(x) = \frac{1}{2}x - 8 \)

However, if the input-output mapping was more like, for instance, \( y = 8x - \frac{1}{2} \), then you would select that form.

Since I lack the specifics of the diagram, I recommend applying these steps directly to the arrows and values in your mapping.
