If I'm not mistaken I believe its
1.) 7/9 = .77
2.) cube root of 8 =2
3.) square root of 5 =2.2
the answer is D
the square root of 6 because it cannot be written as a fraction
Step-by-step explanation:
it is the vertex form.
remember, (h, k) is the vertex point.
the vertex being the point of the (quadratic) parabola, where the curve turns around.
depending on the orientation of the parabola (vertex up or vertex down) as defined by the sign of a, this is either the minimum or the maximum of the curve.
so, the first a. is correct.
and so is the second a., as they play an important role when completing the square and hence finishing the transformation.
I believe your answer is B.
