Question

What is the vertex of the quadratic function below?

y - 3x - 12x +17
O A. (2,5)
O B. (-2,-5)
C. (3, 17)
D. (-3, 17)

Answer 1

`y = - 3 {x}^(2) - 12x + 17 \\ x_0 = ( - b)/(2a ) = (12)/( - 6) = - 2 \\ y_0 = - 3 * {( - 2)}^(2) - 12 * ( - 2) + 17 = 29`

Maybe i did something wrong, maybe your question is incorrect, but the vertex is (-2; 29)

Answer 2

(2,5)
