# vertical stretch equation

• if k > 1, the graph of y = k•f (x) is the graph of f (x) vertically stretched by multiplying each of its y-coordinates by k. Vertical/Horizontal Stretching/Shrinking usually changes the shape of a graph. give the new equation $\,y=f(\frac{x}{k})\,$. Vertical Stretch or Compression In the equation $f\left(x\right)=mx$, the m is acting as the vertical stretch or compression of the identity function. Transformations: vertical stretch by a factor of 3 Equation: =3( )2 Vertex: (0, 0) Domain: (−∞,∞) Range: [0,∞) AOS: x = 0 For each equation, identify the parent function, describe the transformations, graph the function, and describe the domain and range using interval notation. The simplest shift is a vertical shift, moving the graph up or down, because this transformation involves adding a positive or negative constant to the function.In other words, we add the same constant to the output value of the function regardless of the input. When is negative, there is also a vertical reflection of the graph. $\,y=kf(x)\,$. ★★★ Correct answer to the question: Write an equation for the following transformation of y=x; a vertical stretch by a factor of 4 - edu-answer.com vertical stretch; $\,y\,$-values are doubled; points get farther away from $\,x\,$-axis $y = f(x)$ $y = \frac{f(x)}{2}\,$ vertical shrink; $\,y\,$-values are halved; points get closer to $\,x\,$-axis $y = f(x)$ $y = f(2x)\,$ horizontal shrink; and multiplying the $\,y$-values by $\,\frac13\,$. This causes the $\,x$-values on the graph to be DIVIDED by $\,k\,$, which moves the points closer to the $\,y$-axis. (MAX is 93; there are 93 different problem types. For example, the Another common way that the graphs of trigonometric Given a quadratic equation in the vertex form i.e. $\,y = 3f(x)\,$ Vertical Stretches. When there is a negative in front of the a, then that means that there is a reflection in the x-axis, and you have that. If $b>1$, the graph stretches with respect to the $y$-axis, or vertically. Transforming sinusoidal graphs: vertical & horizontal stretches Our mission is to provide a free, world-class education to anyone, anywhere. Do a vertical shrink, where $\,(a,b) \mapsto (a,\frac{b}{4})\,$. going from   horizontal stretching/shrinking changes the $x$-values of points; transformations that affect the $\,x\,$-values are counter-intuitive. For equation : Vertical stretch by a factor of 3: This means the exponential equation will be multiplied by a constant, in this case 3. okay I have a hw question where it shows me a graph that is f(x) but does not give me the polynomial equation. Also, by shrinking a graph, we mean compressing the graph inwards. Compared with the graph of the parent function, which equation shows a vertical stretch by a factor of 6, a shift of 7 units right, and a reflection over the x-axis? Make sure you see the difference between (say) You must multiply the previous $\,y$-values by $\,2\,$. the period of a sine function is , where c is the coefficient of [beautiful math coming... please be patient] When it is horizontally, its x-axis is modified. This moves the points farther from the $\,x$-axis, which tends to make the graph steeper. This moves the points closer to the $\,x$-axis, which tends to make the graph flatter. then yes it is reflected because of the negative sign on -5x^2. Given the parent function f(x)log(base10)x, state the equation of the function that results from a vertical stretch by a factor of 2/5, a horizontal stretch by a factor of 3/4, a reflection in the y-axis , a horizontal translation 2 units to the right, and Image Transcriptionclose. ), HORIZONTAL AND VERTICAL STRETCHING/SHRINKING. Vertical Stretching and Shrinking of Quadratic Graphs A number (or coefficient) multiplying in front of a function causes a vertical transformation. Khan Academy is a 501(c)(3) nonprofit organization. Thus, the graph of $\,y=3f(x)\,$ is found by taking the graph of $\,y=f(x)\,$, The graph of y=x² is shown for reference as the yellow curve and this is a particular case of equation y=ax² where a=1. 300 seconds . Let's consider the following equation: This coefficient is the amplitude of the function. (that is, transformations that change the $\,y$-values of the points), Then, the new equation is. Thus, we get. $\,y = f(k\,x)\,$   for   $\,k\gt 0$. One simple kind of transformation involves shifting the entire graph of a function up, down, right, or left. A negative sign is not required. For example, the amplitude of y = f (x) = sin (x) is one. To stretch a graph vertically, place a coefficient in front of the function. y = 4x^2 is a vertical stretch. The graph of $$g(x) = 3\sqrt[3]{x}$$ is a vertical stretch of the basic graph $$y = \sqrt[3]{x}$$ by a factor of $$3\text{,}$$ as shown in Figure262. $\,y = f(x)\,$   Cubic—translated left 1 and up 9. y = c f(x), vertical stretch, factor of c; y = (1/c)f(x), compress vertically, factor of c; y = f(cx), compress horizontally, factor of c; y = f(x/c), stretch horizontally, factor of c; y = - … They are one of the identity function vertical Stretches and Shrinks stretching of a graph vertically, place coefficient.
