Question

How do you find the axis of symmetry, graph and find the maximum or minimum value of the function `y=2x^2+4x-3`?

Answer 1

To find the coordinates of the maximum or minimum value of any quadratic function, simply plug in `(-b/(2a), (-(b^2))/(4a)+c)` for the equation `f(x)=ax^2+bx+c` The equation for the axis of symmetry is simply `x=-b/(2a)`
