Which equation has a vertex of (- 3 4?
The general equation of a parabola with vertex (h,k) is y=a(x−h)2+k y = a ( x – h ) 2 + k . In this case we have (−3,−4) as the vertex (h,k) and (0,5) is a point (x,y) on the parabola. To find a , substitute the two points in y=a(x−h)2+k y = a ( x – h ) 2 + k .
How do you find the quadratic equation given two points without a vertex?
How do i find the equation of a parabola given 2 points and the axis of symmetry, but no vertex?
- Using the vertex form of a parabola f(x) = a(x – h)2 + k where (h,k) is the vertex of the parabola.
- The axis of symmetry is x = 0 so h also equals 0.
- a = 1.
- Substituting the a value into the first equation of the linear system:
What is the equation of the parabola with vertex 2 4?
Given a parabola with its vertex at the point (2,4) , therefore h=−2,k=4 h = − 2 , k = 4 and we can write y=a(x−2)2+4 y = a ( x − 2 ) 2 + 4 .
