 y = a(x − h)2 k where (h,k) is the vertex of the parabola For your equation that means the vertex is (1,4) Plot this point NOTE there is a sign change for the h but not k NowAnd this is the slope here Now put x zero Then why equals?Divide 1, the coefficient of the x term, by 2 to get \frac {1} {2} Then add the square of \frac {1} {2} to both sides of the equation This step makes the left hand side of the equation a perfect

200以上 y=ax^2 bx c parabola 635543-Focus of parabola y=ax^2+bx+c

Given a quadratic function \(f(x) = ax^2bxc\), it is described by its curve \y = ax^2bxc\ This type of curve is known as a parabola A typical parabola is Y=ax^2bxc 4 a12 b1 c 1 Point 1 12 3×22x8 We can see that c 8 is negative which means that m and n does not have the same signAx2 bxc y a x 2 b x c y Move all terms not containing a a to the right side of the equation The function fx ax2 bx c is a quadratic functionRewrite 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
