Math Problem Statement

Consider the same transformation β„Ž ( π‘₯ )

𝑓 ( 2 π‘₯ βˆ’ 3 ) h(x)=f(2xβˆ’3). Transform the point ( βˆ’ 1 , 0 ) (βˆ’1,0) and select the resulting point on β„Ž ( π‘₯ ) h(x)​.

Solution

To transform the point (βˆ’1,0)(-1, 0) using the given transformation h(x)=f(2xβˆ’3)h(x) = f(2x - 3), follow these steps:

  1. Start with the point: (βˆ’1,0)(-1, 0). The first coordinate is the xx-value, and the second is the yy-value.

  2. Apply the transformation: The transformation given is h(x)=f(2xβˆ’3)h(x) = f(2x - 3), which affects the xx-coordinate. To find the new xx-coordinate, we solve for xx in the expression 2xβˆ’32x - 3.

    Substituting x=βˆ’1x = -1 into 2xβˆ’32x - 3: 2(βˆ’1)βˆ’3=βˆ’2βˆ’3=βˆ’52(-1) - 3 = -2 - 3 = -5 So, x=βˆ’5x = -5 is the transformed xx-coordinate.

  3. Keep the yy-coordinate the same, as it is defined by h(x)=0h(x) = 0. Thus, the point (βˆ’1,0)(-1, 0) transforms to (βˆ’5,0)(-5, 0) under the function h(x)=f(2xβˆ’3)h(x) = f(2x - 3).

Resulting point:

The transformed point on h(x)h(x) is (βˆ’5,0)(-5, 0).

Here are 5 related questions you could explore:

  1. How would the transformation affect a point like (2,3)(2, 3)?
  2. What does the transformation h(x)=f(2xβˆ’3)h(x) = f(2x - 3) do geometrically to the graph of f(x)f(x)?
  3. How would a vertical shift (e.g., h(x)=f(2xβˆ’3)+2h(x) = f(2x - 3) + 2) affect the point (βˆ’1,0)(-1, 0)?
  4. How do transformations of the form h(x)=f(ax+b)h(x) = f(ax + b) impact the domain of f(x)f(x)?
  5. How would you find the inverse of the transformation h(x)=f(2xβˆ’3)h(x) = f(2x - 3)?

Tip: Horizontal transformations involving 2xβˆ’32x - 3 include both a horizontal stretch/compression (due to the factor of 2) and a horizontal shift (due to the βˆ’3-3).
