WebNov 29, 2024 · What determines the horizontal shrink or stretch of a given graph? Key Points If b>1, the graph stretches with respect to the y -axis, or vertically. If b1, the graph shrinks with respect to the y -axis. In general, a horizontal stretch is given by the equation y=f(cx) y = f ( c x ). How do you tell if a graph is a stretch or shrink? WebNov 29, 2024 · To stretch or shrink the graph in the y direction, multiply or divide the output by a constant. 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). Here are the graphs of y = f (x), y = 2f (x), and y = x. Contents [ hide] 1 What is shrinking and stretching?
How do I apply horizontal stretches to logarithmic functions?
WebTo visualize stretches and compressions, we set a > 1 and observe the general graph of the parent function f (x) = logb(x) f ( x) = l o g b ( x) alongside the vertical stretch, g(x)= … WebNov 29, 2024 · To stretch or shrink the graph in the y direction, multiply or divide the output by a constant. 2f (x) is stretched in the y direction by a factor of 2, and f (x) is … can be sought
Stretching, shrinking, and reflecting graphs Algebra 2 Numerade
WebMay 4, 2024 · You will need to compare the graph to that of \(y = \sin x\) or \(y = \cos x\) to see if, in addition to any stretching or shrinking, there has been a reflection over the \(x\)-axis. The graph above on the right can be thought of as the result of stretching and reflecting the graph of \(y = \sin x\) across the \(x\)-axis. WebSine and Cosine functions (Stretching&Shrinking) Sinx and cosx are the two basic and frequently used trigonometric functions. Their graphs have same properties. Lets have a look at these properties. Domain of both sinx and cosx is all real numbers (-∞ , ∞). Range of each function is [-1,1]. WebTo stretch a graph vertically, place a coefficient in front of the function. This coefficient is the amplitude of the function. For example, the amplitude of y = f (x) = sin (x) is one. The amplitude of y = f (x) = 3 sin (x) is three. Compare the two graphs below. Figure %: The sine curve is stretched vertically when multiplied by a coefficient. can besora drive
