graph

Graph each transformed function

Solution

To graph each transformed function, let's break down the transformations one by one for each function.

1. f(x)=2x+15f(x) = -2|x + 1| - 5

This is an absolute value function with the following transformations:

  • Horizontal shift: x+1x + 1 means a shift 1 unit to the left.
  • Vertical shift: The 5-5 moves the graph 5 units down.
  • Vertical stretch: The 2-2 multiplies the absolute value, flipping the graph upside down and stretching it vertically by a factor of 2.

Vertex: (1,5)(-1, -5)

2. g(x)=(x1)22g(x) = (x - 1)^2 - 2

This is a quadratic function with:

  • Horizontal shift: x1x - 1 means a shift 1 unit to the right.
  • Vertical shift: The 2-2 moves the graph 2 units down.

Vertex: (1,2)(1, -2)

3. h(x)=(x6)h(x) = \sqrt{-(x - 6)}

This is a square root function, which has been reflected and shifted:

  • Reflection: The negative sign inside the square root reflects the graph across the y-axis.
  • Horizontal shift: x6x - 6 moves the graph 6 units to the right.

Starting point: (6,0)(6, 0)

4. m(x)=x6m(x) = \sqrt{-x - 6}

This is also a square root function, with different transformations:

  • Reflection: The x-x reflects it across the y-axis.
  • Horizontal shift: The 6-6 moves the graph 6 units left.

Starting point: (6,0)(-6, 0)

5. n(x)=13(x+3)2+4n(x) = \frac{1}{3}(x + 3)^2 + 4

This is a quadratic function that has been compressed and shifted:

  • Horizontal shift: x+3x + 3 moves the graph 3 units to the left.
  • Vertical shift: The +4+4 moves the graph 4 units up.
  • Vertical compression: The 13\frac{1}{3} compresses the graph vertically.

Vertex: (3,4)(-3, 4)

6. p(x)=4x+51p(x) = 4\sqrt{x + 5} - 1

This is a square root function that has been stretched and shifted:

  • Horizontal shift: x+5x + 5 moves the graph 5 units to the left.
  • Vertical shift: The 1-1 moves the graph 1 unit down.
  • Vertical stretch: The 4 stretches the graph vertically.

Starting point: (5,1)(-5, -1)

7. r(x)=34x5+4r(x) = \frac{3}{4}|x - 5| + 4

This is another absolute value function:

  • Horizontal shift: x5x - 5 moves the graph 5 units to the right.
  • Vertical shift: The +4+4 moves the graph 4 units up.
  • Vertical compression: The 34\frac{3}{4} compresses the graph vertically.

Vertex: (5,4)(5, 4)


Would you like me to show the graphs or provide more details on any specific function?

Here are some related questions to explore:

  1. How does a horizontal shift affect the shape of a function's graph?
  2. What impact does a vertical stretch or compression have on the graph of a function?
  3. How do absolute value transformations affect the slope of the graph?
  4. How would you graph a reflection across the x-axis for any given function?
  5. What is the domain and range for square root functions after transformations?

Tip: When graphing transformed functions, always start with the basic shape of the function (like x|x|, x2x^2, or x\sqrt{x}) and apply each transformation step-by-step.
