Give me every partner function and the way it moves

Solution

Let's break down each function given in the image. I will describe the transformations applied to each parent function f(x)f(x), as well as how the graph of g(x)g(x) is transformed from its parent function.

24. g(x)=3x4g(x) = 3|x| - 4

  • Parent function: f(x)=xf(x) = |x| (Absolute value function)
  • Transformations:
    1. Vertical stretch by a factor of 3 (the 3 in front of x|x|).
    2. Vertical shift downward by 4 units (the 4-4).

25. g(x)=3x+8g(x) = 3\sqrt{x} + 8

  • Parent function: f(x)=xf(x) = \sqrt{x} (Square root function)
  • Transformations:
    1. Vertical stretch by a factor of 3 (the 3 in front of x\sqrt{x}).
    2. Vertical shift upward by 8 units (the +8+8).

26. g(x)=4x+1g(x) = \frac{4}{x+1}

  • Parent function: f(x)=1xf(x) = \frac{1}{x} (Reciprocal function)
  • Transformations:
    1. Horizontal shift left by 1 unit (the +1+1 inside the denominator).
    2. Vertical stretch by a factor of 4 (the 4 in the numerator).

27. g(x)=2x6g(x) = 2|x - 6|

  • Parent function: f(x)=xf(x) = |x|
  • Transformations:
    1. Horizontal shift right by 6 units (the 6-6 inside the absolute value).
    2. Vertical stretch by a factor of 2 (the 2 in front of x6|x - 6|).

28. g(x)=5x2g(x) = -5|x - 2|

  • Parent function: f(x)=xf(x) = |x|
  • Transformations:
    1. Horizontal shift right by 2 units (the 2-2 inside the absolute value).
    2. Vertical stretch by a factor of 5.
    3. Reflection across the x-axis (because of the negative sign in front of the 5).

29. g(x)=2x+5g(x) = -2|x + 5|

  • Parent function: f(x)=xf(x) = |x|
  • Transformations:
    1. Horizontal shift left by 5 units (the +5+5 inside the absolute value).
    2. Vertical stretch by a factor of 2.
    3. Reflection across the x-axis (the negative sign in front of 2).

30. g(x)=16x+7g(x) = \frac{1}{6x} + 7

  • Parent function: f(x)=1xf(x) = \frac{1}{x}
  • Transformations:
    1. Horizontal compression by a factor of 1/61/6 (the 6x6x in the denominator).
    2. Vertical shift upward by 7 units (the +7+7).

31. g(x)=x+34g(x) = \frac{\sqrt{x + 3}}{4}

  • Parent function: f(x)=xf(x) = \sqrt{x}
  • Transformations:
    1. Horizontal shift left by 3 units (the +3+3 inside the square root).
    2. Vertical compression by a factor of 4 (the division by 4).

Would you like further details on any of the transformations, or do you have any questions about these functions?

Here are 5 additional related questions to expand on this topic:

  1. What is the parent function of g(x)=x+3g(x) = -|x| + 3, and how does it move?
  2. How would the graph of g(x)=2x41g(x) = 2\sqrt{x - 4} - 1 be transformed?
  3. What happens if the coefficient inside an absolute value function is negative, like in g(x)=x2+5g(x) = -|x - 2| + 5?
  4. How does horizontal stretching or compression affect the graph of a function?
  5. What are the key differences between vertical and horizontal transformations?

Tip: Always remember that vertical transformations affect the output (y-values), while horizontal transformations affect the input (x-values).
