WebUnfortunately, he missed a quiz and received a zero on that quiz. Luckily, h is kindly old statistics professor will drop h is lowest quiz grade. H [ Z v µ]ÌÌ es, and the average (mean) of h is quiz grades with the zero is 15.3. What will h is average be when the professor drops the zero? (a) 16.8 (b) 17 (c) 17.3 (d) 18 WebAnd Sal told that to obtain the vertex form the Part A ( x + B )^2 should be equal to zero in both the cases. And for that (x+ (b/2a)) should be equal to zero. And now we can derive that as follows: x + (b/2a) = 0 => x = -b/2a. And here your formula is whose deriving seems pretty daunting but is based on just simple logical reasoning.

Parabola - Math

WebA parabola is going to follow the form [math]y = r (x-x_1) (x-x_2) [/math] where [math]r [/math] is a constant, and [math]x_1 [/math] and [math]x_2 [/math] are the functions roots. So if we’re given a function’s zeros, you … WebThe general equation of a parabola is: y = a (x-h) 2 + k or x = a (y-k) 2 +h, where (h,k) denotes the vertex.
