How is the graph of y = x^2 + 2x – 3 related to its parent function, y = x^2?
The graph of y = x^2 + 2x – 3 is a quadratic function that can be written in the form y = a(x – h)^2 + k, where a, h and k are constants. This form is called the vertex form of a quadratic function. The parent function of y = x^2 + 2x … Read more
