Help Please! Describe the transformation of the graph of f into the graph of g as either a horizontal or vertical stretch.


f as a function of x is equal to the square root of x and g as a function of x is equal to 3 times the square root of x.


I know it's a vertical stretch but I can't explain it.

Verified Answer :

\(f(x) = \sqrt{x} \\ g(x) = 3 \sqrt{x} \\ \\ g(x) = 3f(x)\)

That would be a vertical stretch. Hope this is what you are looking for?

Since function g is a multiplication of function f, and the multiplication coefficient is greater than 1, it is a vertical stretch.

---------------------------------

This question is solved stretching concepts.

  • Vertically stretching a function f(x) in b units is the same as finding \(bf(x)\), considering b > 1.
  • Horizontally stretching a function f(x) in b units is the same as finding \(f(b(x))\)

---------------------------------

The functions are:

\(f(x) = \sqrt{x}\)

\(g(x) = 3\sqrt{x}\)

Since function g is a multiplication of function f, and the multiplication coefficient is greater than 1, it is a vertical stretch.

The image at the end of this answer shows the original function f, in red, and the horizontally stretched function g, in blue.
