The focus of this paper is to determine the characteristics of parabolas in the form y = a(x h) 2 k For our purposes, we will call this second form the shiftform equation of a parabola Given a quadratic in this form, it is fairly easy to predict the general shape of the parabola By examining a coefficient and the values for h and k, itF(x) = x^24kx(311k) where k is a constant 1 (I have no problem with this question but i'll just mention it) Express f(x) in the form (xp)^2 q, where p andq are constants to be found in terms of kThe simplest exponential, the general form, is defines as f(x)=2 x However, as you probably know from previous experience, graphs are generally not this friendly and simple They can shift, flip, and change in shape depending on coefficients and other values applied to the general form
