Question

Sketch the graph of the following quadratic function by method of factoring or Quadratic formula to locate the x-intercepts and finding the coordinates of the vertex.

y = x²- 6x +8

Formula Formula A polynomial with degree 2 is called a quadratic polynomial. A quadratic equation can be simplified to the standard form: ax² + bx + c = 0 Where, a ≠ 0. A, b, c are coefficients. c is also called "constant". 'x' is the unknown quantity
