In the next few questions, we will find the roots of the general equation y = a x 2 b x with a ≠ 0 by factoring, and use that to get a formula for the axis of symmetry of any equation in that form Question 5 We want to factor a x 2 b x Because both terms contain an x, We learned from the video lesson that the b value in the quadratic equation y = ax2 bx c affects the location of the parabola Each parabola has the same a value Each parabola has the same a valueThe graph of y = ax^2 bx c is called a quadratic function

Y=ax2+bx+c how to find b-Exploring Parabolas by Kristina Dunbar, UGA Explorations of the graph y = ax 2 bx c In this exercise, we will be exploring parabolic graphs of the form y = ax 2 bx c, where a, b, and c are rational numbers In particular, we will examine what happens to the graph as we fix 2 of the values for a, b, or c, and vary the third We have split it up into three partsRewrite the equation as ax2 bx c = y a x 2 b x c = y Move y y to the left side of the equation by subtracting it from both sides Use the quadratic formula to find the solutions Substitute the values a = a a = a, b = b b = b, and c = c−y c = c y into the quadratic formula and solve for x x Simplify the numerator

Mathematics Middle School answer answered The graph of y = ax 2 bx c is a parabola that opens up and has a vertex at (2, 5) The focus turns out to be at $(\frac{b}{2a},\frac{1b^2}{4a}c)$ Notice how the vertex and focus are lying on the same line That's to be expected with the equation for "vertical" parabolas that you described Solution Get the equation in the form y = ax2 bx c Calculate b / 2a This is the xcoordinate of the vertex To find the ycoordinate of the vertex, simply plug the value of b / 2a into the equation for x and solve for y This is the ycoordinate of the vertex
Of that vague equation, the X coordinate is at b/2a To find the Y coordinate, plug it back in Now if you would like to do this the calculus way, differentiate the equation, and set the resulting 2ax = b and solve for X Then, plug the X backThis is your generic quadratic equation y = ax 2 bx c Move the loose number over to the other side y – c = ax 2 bx Factor out whatever is multiplied on the squared term Make room on the lefthand side, and put a copy of " a " in front of this spaceAnswer y = ax2 bxc The vertex will correspond to the point where the curve attains a minima (a> 0) or maxima (a < 0) ∴ dxdy = 2axb = 0 ⇒ x = 2a−b

The square root of the same, less the coefficient of the middle term, beingYour equation will have the formula y = Ax^2 Bx C (writing it as Ax^2 Bx C = y may help your math) Your three (x, y) points can be plugged into this formula to to get a system of three equations in A, B, and C, which can be solved by substitution or elimination to obtain A, B, and CThe formula for the x position of the vertex is Now using the points, Now substitute for b
