Math Problem Statement

Write an equation for the function f(x) = |x|, but shifted 6 units to the left and 8 units down. Then, use the graph of f(x) = |x| to write an equation for another shifted function based on the graph.

Solution

Let's break down the two problems presented in the image.

Problem 1:

You are asked to write an equation for the function f(x)=xf(x) = |x|, but shifted 6 units to the left and 8 units down.

  • Shifting a function horizontally by hh units to the left is done by replacing xx with x+hx + h.
  • Shifting a function vertically by kk units down is done by subtracting kk from the function.

For this function:

  • The shift of 6 units to the left means x+6x + 6.
  • The shift of 8 units down means subtracting 8.

Thus, the equation becomes: g(x)=x+68g(x) = |x + 6| - 8

Problem 2:

You are asked to write an equation based on the graph of f(x)=xf(x) = |x|.

Looking at the graph (though it's hard to see specific details), it seems like a standard absolute value function that might be shifted. To write the correct equation, you would observe:

  • Any horizontal or vertical shifts,
  • Any changes in the slope or reflection, and
  • The vertex's coordinates.

However, with only a partial image of the graph, I'd need more details to provide the specific equation.

Would you like a deeper explanation for these transformations, or should I help you analyze the second part further? Here are some related questions to consider:

  1. What happens if you shift the function 6 units to the right instead of left?
  2. How would you adjust the equation if the graph is reflected over the x-axis?
  3. What if the function was shifted up instead of down—how would the equation change?
  4. How do you describe a vertical stretch or compression of the absolute value function?
  5. How would the equation change if the vertex of the absolute value graph was shifted to a different point?

Tip: Always keep track of the transformations by modifying xx for horizontal shifts and applying operations directly to the function for vertical shifts.
