Math Problem Statement

Write an equation of the function g(x) that is the graph of f(x) = |x|, but shifted left 6 units and shifted down 7 units.

Solution

The original function given is f(x)=xf(x) = |x|.

Now, we are asked to shift this function:

  1. Left by 6 units: Shifting a function left by 6 units modifies the argument of the function. For a shift left, we add 6 to xx. So the new function becomes x+6|x + 6|.
  2. Down by 7 units: Shifting a function down by 7 units means subtracting 7 from the function value. So we subtract 7 from the expression.

Thus, the new equation for the function g(x)g(x) after shifting becomes: g(x)=x+67g(x) = |x + 6| - 7

Would you like a detailed breakdown of how shifts in functions work?

Here are 5 related questions:

  1. How do horizontal and vertical shifts affect the graph of a function?
  2. What happens to the graph of f(x)=xf(x) = |x| if it is shifted right instead of left?
  3. How can you determine shifts based on the equation of a function alone?
  4. What would the graph look like if you shifted the function up instead of down?
  5. How do reflections (flipping) relate to translations in functions?

Tip: Horizontal shifts affect the xx-variable inside the function (e.g., x+cx + c for left), while vertical shifts affect the entire function by adding or subtracting a constant.
