NettetREFLECTION TOPIC – LINES AND QUADRATIC FUNCTIONS. Question 1: Reflect on the concept of lines and quadratic functions. Answer (Preamble): I will briefly explain what linear function is, give some basic examples of linear function and also explain the general formula for a linear function. In addition, I will explain what quadratic function is give a … Nettetthe quadratic formula. These are described in the appendix. The line of symmetry can also be found from the formula below. The parabola y ax2 bx c has line of symmetry x b 2a. –1 2 y x The midpoint of –1 and 2 is ( 1) 2 2. The vertex is on the line of symmetry. –1 2 y • (1/2, 9/4) x Solve by factorising.

Nettet30. jul. 2016 · The quadratic equation is . The line of symmetry is x =2. We know that the graph of quadratic function is a parabola and the line of symmetry of a parabola always passes through the vertex. The line of symmetry is x =2. And the x-coordinate of the vertex is . Hence, we have. Thus, the value of a is 2 NettetFor a parabola with quadratic equation y = ax 2 + bx + c, the line symmetry equation is of the form x = n, where n is a real number. The line of symmetry equation is given by, x = -b/2a. Let us solve an example to understand it better. Example: Find the line of symmetry of parabola y = x 2 + x - 5 Solution: Identify a, b, c in the given equation. common room logo
