Math Problem Statement

or Find g(x), where g(x) is the translation 8 units up of f(x)=|x|. Write your answer in the form a|x–h|+k, where a, h, and k are integers. g(x)=

Solution

To find the function g(x)g(x) that represents the translation of f(x)=xf(x) = |x| 8 units up, we modify the equation by adding 8 to the output of the function.

The original function is:

f(x)=xf(x) = |x|

When translating a function upward by kk units, we add kk to the function:

g(x)=f(x)+8=x+8g(x) = f(x) + 8 = |x| + 8

Now, the given form is axh+ka|x - h| + k. In this case:

  • a=1a = 1 (since the slope of the absolute value is unchanged),
  • h=0h = 0 (there's no horizontal shift),
  • k=8k = 8 (the vertical translation).

Thus, the function becomes:

g(x)=1x0+8g(x) = 1|x - 0| + 8

Simplified:

g(x)=x+8g(x) = |x| + 8

Would you like further details or have any questions?

Here are 5 related questions for you:

  1. How would the equation change if we translated f(x)=xf(x) = |x| 5 units down instead?
  2. What happens to the graph of f(x)=xf(x) = |x| when translated 3 units to the right?
  3. How do you find the horizontal translation of f(x)=xf(x) = |x|?
  4. If f(x)=2xf(x) = 2|x|, what is the translation 8 units up?
  5. What are the effects of translating a function both horizontally and vertically?

Tip: Vertical translations simply add or subtract from the function's output, while horizontal translations affect the input inside the function.
