Math Problem Statement

The equation for the transformed function is g(x) = -0.5x + 1. Indicate the transformation(s) of the basic linear function f(x) = x needed to create g(x).

Solution

The image you've uploaded shows a problem related to the transformation of linear functions. The goal is to identify the transformations applied to the basic linear function f(x)=xf(x) = x to produce the transformed function g(x)=0.5x+1g(x) = -0.5x + 1.

Let's break down the transformation step-by-step:

  1. Reflection: The negative sign in front of the coefficient of xx in g(x)=0.5x+1g(x) = -0.5x + 1 suggests a reflection over the x-axis. This is because multiplying by a negative number reflects the graph vertically.

  2. Dilation (Vertical Scaling): The coefficient of xx is 0.5-0.5, which means that the graph of the basic function f(x)=xf(x) = x is vertically compressed by a factor of 0.5. This is a vertical scaling transformation that shrinks the slope of the line.

  3. Vertical Translation: The constant term +1+1 indicates a vertical shift. This translates the entire graph of the function upwards by 1 unit.

Summary of Transformations:

  • Reflection over the x-axis.
  • Vertical Dilation by a factor of 0.5.
  • Vertical Translation up by 1 unit.

Would you like further clarification on any of these transformations?

Here are five related questions to deepen your understanding:

  1. How would the transformation change if the coefficient of xx was positive?
  2. What happens to the graph of the function if the vertical translation was negative?
  3. How does a horizontal translation differ from a vertical translation in linear functions?
  4. How does the slope of a linear function affect the steepness of the graph?
  5. How would you apply multiple transformations in a different order, such as reflecting after translating?

Tip: Remember that reflections change the direction of the graph, but dilations modify the steepness or flatness of the slope.
