# Functions - Stretches - Practice

• Given a random function and a random stretch of that function (of the form $$g(x)=af(bx)$$), determine what $$a,b$$ must be
• Watch the individual stretches to see if your $$a,b$$ values are correct
• Keep practicing with random functions

## Directions

• Use the coordinates of the given points to determine $$a,b$$
• Enter your values for $$a,b$$ in the boxes
• Click Stretch buttons to see the individual stretches
• Click Reset if your $$a,b$$ values are incorrect
• Click New f(x) to get two new random functions

Note: The point ∙ is always transformed to ∘, and the point ⧫ is always transformed to ◊.
