WebFeb 5, 2024 · ★ Use the vertex (h, k) and a point on the graph (x, y) to find the general form of the equation of the quadratic function. 223) (h, k) = (2, 0), (x, y) = (4, 4) 224) (h, k) = ( − 2, − 1), (x, y) = ( − 4, 3) 225) (h, k) = (0, 1), (x, y) = (2, 5) 226) (h, k) = (2, 3), (x, y) = (5, 12) 227) (h, k) = ( − 5, 3), (x, y) = (2, 9) WebKey Takeaways. 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 vertical stretch is given by the equation y=bf (x) y = b f ( x ) . …. In general, a horizontal stretch is given by the equation y=f (cx) y = f ( c x ) .

WebNov 1, 2024 · The graph is the basic quadratic function shifted 2 units to the right, so g(x) = f(x − 2) Notice how we must input the value x = 2 to get the output value y = 0; the x -values must be 2 units larger because of the shift to the right by 2 units. We can then use the definition of the f(x) function to write a formula for g(x) by evaluating f(x − 2). WebFigure 274 Explore the properties of horizontal stretches and compressions discussed in this section with this applet. You can change the base function \(f(x)\) using the input box and see many different stretches/compressions of \(f(x)\) by moving around the \(a\) slider. Subsection Supplemental Videos.
