WebHow To: Given a description of a function, sketch a horizontal compression or stretch. Write a formula to represent the function. Set g(x) = f (bx) g ( x) = f ( b x) where b> 1 b > 1 for a … WebFigure 4. Another Parabola Scaling and Translating Graphs. The principles illustrated here apply to any equation, so let's restate them: A combination of horizontal and vertical shifts is a translation of the graph, a combination of horizontal and vertical compression and stretching is a scaling of the graph. Adding a constant to shifts the graph units to the right …

WebNov 19, 2024 · y = a (x - h)2 + k . And if the parabola opens horizontally (which can mean the open side of the U faces right or left), you'll use this equation: x = a (y - k)2 + h . Because the example parabola opens vertically, let's use the first equation. Next, substitute the parabola's vertex coordinates (h, k) into the formula you chose in Step 1.

Horizontal and Vertical Stretching/Shrinking
WebOct 6, 2024 · As you will soon see, the constant a controls the scaling (stretching or compressing of the parabola), the constant h controls a horizontal shift and placement of … WebDec 13, 2024 · When you stretch a function horizontally, you need a greater number for x to get the same number for y. For example, say that in the original function, you plugged in 5 for x and got out 10 for y . WebStep 1: Find a few points on the graph. Suppose the points are (x1,y1),(x2,y2),(x3,y3) ( x 1, y 1), ( x 2, y 2), ( x 3, y 3) . Step 2: When we reflect a point across the y y -axis, its vertical ... nottingham forest next home game
