I'm going to do the horizontal stretch of 1/3. 2 - The graph is shifted to the right units. Let’s proceed and consider how f ( x) = x2 will undoubtedly be influenced by a scale aspect of 1/2 and 1/3. The vertex of a parabola is the lowest point on a parabola that opens up, and the highest point on a parabola that opens down. Let g(x) be the transformation of f(x)= 3x - 5 when it is translated 6 units up followed by a horizontal stretch by a factor of 3/2. horizontal stretch of a graph by a factor of n makes f (x) as f (x/n) since your graph is stretched by a factor of 5, your f (x) is transformed to f (x/5) = x/5. 8. Required fields are marked * Comment. We can also stretch and shrink the graph of a function. Shrink the graph of f vertically by a factor of \(\frac{1}{3}\). Hence, we have h(x) = 2(x – 1) 2.
