FYI: Different textbooks have different interpretations of the reference standard form of a quadratic function. Some say f (x) = ax2 + bx + c is standard form, while others say that f (x) = a(x - h)2 + k is standard form.
So, as we can see, being able to use the quadratic formula is quite important when graphing quadratic functions! Graph the quadratic functions below by finding the y-intercept, the x-intercept(s) and the vertex of each function. 1. f(x) = - x2 - 4x + 1. 2. f(x) = 2 (x + 1)2 - 7.
