## anonymous one year ago Which of the following is the vertex of the function? y = x2 - 14x + 13 a: (1, 0) b: (3, -20) c: (5, -32) d: (7, -36)

easy method to find vertex formula to find x coordinate of vertex $\huge\rm x=\frac{ -b }{ 2a }$ then plug n x value into the equation ,solve for y (a is leading coefficient , b =middle term )
