Find the equation of the quadratic function with zeros 16 and 18 and a vertex at (17, -2). y= x2 − 34x + 288
y = 2x2 − 68x + 576
y = x2 + 34x + 288
y = -2x2 + 68x − 576

Question

Find the equation of the quadratic function with zeros 16 and 18 and a vertex at (17, -2).           y= x2 − 34x + 288 
   y = 2x2 − 68x + 576 
   y = x2 + 34x + 288 
   y = -2x2 + 68x − 576

mathmale · Answer

When the vertex of a parabola (quadratic function) is known, and is at (h,k), the proper equation to use is $$y=a(x-h)^2+k$$     Use this fact and the information contained in the two zeros to find the value of the coefficient 'a'.  Then write the equation of the parabola.
