Find the parabola through ( 5 , − 1 ) ( 5 , - 1 ) with vertex ( − 3 , 5 ) ( - 3 , 5 ) using the vertex form y = a ( x − h ) 2 + k y = a ( x - h ) 2 + k . Standard Form: y = − 3 32 x 2 − 9 16 x + 133 32 y = - 3 32 x 2 - 9 16 x + 133 32 Vertex Form: y = − 3 32 ( x + 3 ) 2 + 5 y = - 3 32 ( x + 3 ) 2 + 5
