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 spaceRewrite 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 numeratorTry varying the values of a and k and examine what effects this has on the graph
If the graph of $y = f(x) = ax^2 bx c$ passes through $(1,0)$ and $(3,0)$ this means that $f(1) = 0$ and $f(3) = 0$ One such quadratic polynomial is $$ f(x) = (x1)(x3) = x^2 4x 3 $$ Since multiplying the polynomial $f(x)$ by a real number $k$ will not influence the value of $f(x)$ at $1$ and $3$ we find that the graph of $$ f(x) = k(x1)(x3) = k(x^2 4x 3) $$ also passes throughIsolating "y" and then making a function with the quadratic formula to x deltaThe vertex is on the axis of symmetry, so its $x$coordinate is 3 The vertex is also a point on the parabola, so it satisfies the equation for the parabola This means that if you plug the $x$coordinate of the vertex into the equation, you will get the $y$coordinate Plugging 3 for $x$ into $y=x^26x$ gives $y=(3)^26(3)$ → $y=918$ → $y=9$
From eqations (4)and (5) we get a= 3 and b= 2 at last c=5 so the equation of parabola in the form y=ax^2byc will be y= 3x^2 2x5 Note the equation of above parabola in standard form is (x1/3)^2= 1/3(y 16/3) The prabola has a point Max ( 1/3 ;Examples ax^2bxc=0 x^2x6=9 x^2x6=0 x^21=0 x^22x1=3x10 2x^24x6=0 quadraticequationcalculator ax^2bxc=0 To calculate the axis of symmetry for a 2nd order polynomial in the form ax 2 bx c (a parabola), use the basic formula x = b / 2a In the example above, a = 2 b = 3, and c = 1 Insert these values into your formula, and you will get x = 3 / 2 (2) = 3/4 Write down the equation of the axis of symmetry
