Math Problem Statement

Graph the given​ functions, f and​ g, in the same rectangular coordinate system. Describe how the graph of g is related to the graph of f. f left parenthesis x right parenthesis equals StartAbsoluteValue x EndAbsoluteValue ​g(x) equals StartAbsoluteValue x EndAbsoluteValueplus5

Solution

The graph of f(x)=xf(x) = |x| is the standard V-shaped absolute value function, while the graph of g(x)=x+5g(x) = |x| + 5 is the same V-shaped function, but shifted 5 units upward.

Relationship:

The graph of g(x)g(x) is a vertical translation of f(x)f(x). Specifically, g(x)g(x) is obtained by moving the graph of f(x)f(x) up by 5 units.

Do you want more details or have any questions?

Here are some related questions for further exploration:

  1. How would the graph of g(x)=x3g(x) = |x| - 3 compare to f(x)f(x)?
  2. What happens if you subtract a constant from x|x|, e.g., f(x)=x2f(x) = |x| - 2?
  3. How would the graph change if you multiply x|x| by a constant, say 2x2|x|?
  4. What is the effect of adding or subtracting from the xx-variable inside x|x|?
  5. How does the vertex of f(x)=xf(x) = |x| shift with vertical or horizontal translations?

Tip: Vertical shifts occur when constants are added or subtracted to the entire function.
