16-week Lesson 21 (8-week Lesson 17) Vertical and Horizontal Stretching and Compressing 3 right, In this transformation the outputs are being multiplied by a factor of 2 to stretch the original graph vertically Since the inputs of the graphs were not changed, the graphs still looks the same horizontally. If a1 , then the graph will be stretched. g (x) = (1/2) x2. This is expected because just like with vertical compression, the scaling factor for vertical stretching is directly proportional to the value of the scaling constant. If a graph is vertically stretched, those x-values will map to larger y-values. Remember, trig functions are periodic so a horizontal shift in the positive x-direction can also be written as a shift in the negative x-direction. A horizontal compression (or shrinking) is the squeezing of the graph toward the y-axis. If you need help, our customer service team is available 24/7. That was how to make a function taller and shorter. Vertical Stretches, Compressions, and Reflections As you may have notice by now through our examples, a vertical stretch or compression will never change the. Let's look at horizontal stretching and compression the same way, starting with the pictures and then moving on to the actual math. If [latex]a>1[/latex], then the graph will be stretched. A General Note: Horizontal Stretches and Compressions 1 If b > 1 b > 1, then the graph will be compressed by 1 b 1 b. To compress the function, multiply by some number greater than 1. You can get an expert answer to your question in real-time on JustAsk. The constant value used in this transformation was c=0.5, therefore the original graph was stretched by a factor of 1/0.5=2. Horizontal and Vertical Stretching/Shrinking If the constant is greater than 1, we get a vertical stretch if the constant is between 0 and 1, we get a vertical compression.

Points on the graph of $\,y=f(3x)\,$ are of the form $\,\bigl(x,f(3x)\bigr)\,$. Vertical compression is a type of transformation that occurs when the entirety of a function is scaled by some constant c, whose value is between 0 and 1. A constant function is a function whose range consists of a single element. When |b| is greater than 1, a horizontal compression occurs. $\,y = f(3x)\,$! we're multiplying $\,x\,$ by $\,3\,$ before dropping it into the $\,f\,$ box. Vertical stretch occurs when a base graph is multiplied by a certain factor that is greater than 1. When by either f (x) or x is multiplied by a number, functions can "stretch" or "shrink" vertically or horizontally, respectively, when graphed. In general, a horizontal stretch is given by the equation y=f (cx) y = f ( c x ). See how we can sketch and determine image points.

Adding a constant to the inputs or outputs of a function changed the position of a graph with respect to the axes, but it did not affect the shape of a graph. Look at the value of the function where x = 0. How can you stretch and compress a function? Notice that we do not have enough information to determine [latex]g\left(2\right)[/latex] because [latex]g\left(2\right)=f\left(\frac{1}{2}\cdot 2\right)=f\left(1\right)[/latex], and we do not have a value for [latex]f\left(1\right)[/latex] in our table. In other words, if the scaling constant is between 0 and 1, it means that the scaling is horizontal; if it is greater than 1, it means that the scaling is horizontal. The input values, [latex]t[/latex], stay the same while the output values are twice as large as before. Explain: a. Stretching/shrinking: cf(x) and f(cx) stretches or compresses f(x) horizontally or vertically. Math can be a difficult subject for many people, but it doesn't have to be! Instead, that value is reached faster than it would be in the original graph since a smaller x-value will yield the same y-value.
Wed love your input. The most conventional representation of a graph uses the variable x to represent the horizontal axis, and the y variable to represent the vertical axis. To determine the mathematical value of a sentence, one must first identify the numerical values of each word in the sentence. Since we do vertical compression by the factor 2, we have to replace x2 by (1/2)x2 in f (x) to get g (x). Again, the minimum and maximum y-values of the original function are preserved in the transformed function. Observe also how the period repeats more frequently.
