WebStudents will use vertex form to graph quadratic functions and describe the transformations from the parent function with 70% accuracy. The parent function f(x) = x2 is vertically stretched by a factor of 4/3 and then translated 2 units left and 5 units down. Use the description to write the quadratic function in vertex form. WebFirstly, we know h and k (at the vertex): (h, k) = (1, 1) So let's put that into this form of the equation: f (x) = a (x-h)2 + k f (x) = a (x−1)2 + 1 Then we calculate "a": We know the point (0, 1.5) so: f (0) = 1.5 And a (x−1)2 + 1 at x=0 is: f (0) = a (0−1)2 + 1 They are both f (0) so make them equal: a (0−1)2 + 1 = 1.5 Simplify: a + 1 = 1.5

WebHow to Graph a Parabola in Vertex Form Step 1: Use the vertex form provided to determine the vertex of the function. Graph this point. The general vertex form of a function is f(x) =... WebStep - 1: Compare the equation of the parabola with the vertex form x = a (y - k) 2 + h and identify the values of h and k. By comparing x = 2 (y + 3) 2 + 5 with the above equation, … WebDec 26, 2014 · Firstly, you need to find the vertex . This is derived through (wait for it) vertex form. In the equation y = a(x −h)2 + k, the point (h,k) is your vertex. It is either the highest or lowest point on your graph, and it is the first thing you need to graph. For example, consider the equation y = −2(x − 6)2 +2 patati et patasucre
