Step 2 : So, the formula that gives the requested transformation is y = √0.5x Step 3 : The graph y = √0.5x can be obtained by expanding the graph of … Let’s proceed and consider how f ( x) = x2 will undoubtedly be influenced by a scale aspect of 1/2 and 1/3. Aregular hexagon rotates counterclockwise about its center. 2 units up -> k = 2. reflection in y axis -> x value is negative. If you then stretched horizontally by a factor of 2 you multiply the x-values by 2. To stretch a function horizontally by factor of n the transformation is just f (x/n). Write (a) a function g whose graph is a horizontal shrink of the graph of f by a factor of 1— 3, and (b) a function h whose graph is a vertical stretch of the graph of f by a factor of 2. a indicates a reflection in the x-axis and/or a vertical stretch or shrink. A horizontal stretch is the stretching of a function on the y-axis. The dashed graph is f(x/2), stretched by a factor of 2 horizontally; the point (2, 4) moves to (4, 4), doubling x. I first looked at the more natural vertical transformations from a new perspective: Adjust the graph of the parent function to match the vertical and horizontal shift in the original graph. In the above example, if the function has a vertical shift of 1 and a horizontal shift of pi, adjust the parent function p(x) = sin x to p1(x) = A sin (x - pi) + 1 (A is the value of the vertical stretch, which we have yet to determine). Let g(x) be a horizontal shift of f(x) = 3x, left 6 units followed by a horizontal stretch by a factor of 4. f ( x). The parent function f (x) = √ x is stretched horizontally by a factor of 2, reflected across the y-axis, and translated 3 units left. - The graph is shifted to the right units. A horizontal stretch is one in which a figure is stretched to the left or the right. Hence, we have h(x) = 2(x – 1) 2. }\) However, what you might have observed is how the y values remained the same. y = 3 sin 2x The equation has the general form y = a sin— x. Value by two And draw it in next.

REASONING The graph of g(x) = -4 |x | + 2 is a reflection in the x-axis, vertical stretch by a factor of 4, and a translation 2 units down of the graph of its parent function. The new zeros of the function are -3, -2, 1 C. The new y-intercept is -96 D. The new y-intercept is -24 … Hence, we have (6, 4) → (2 ∙ 6, 4). Vertex at (4,2), opening left with a horizontal stretch by a factor of 3. Thus, the equation of a function stretched vertically by a factor of 2 and then shifted 3 units up is y = 2f (x) + 3, and the equation of a function stretched horizontally by a factor of 2 and then shifted 3 units right is y = f ((x - 3)) = f (x - ). 2f (x) is stretched in the y direction by a factor of 2, and f (x) is shrunk in the y direction by a factor of 2 (or stretched by a factor of ). This is a horizontal stretch by a factor of 3 the. Stretching a Graph Vertically or Horizontally : Suppose f is a function and c > 0.
