A. -4
B. -6
C. 6
D. 4

Answer 1

1) Don't post questions with no work shown.
2) Have you considered constructing the equation? You have the vertex and an additional point. That's all you need.

Answer 2

Do you know the equation of the graph?

Answer 3

Without the equation, you will not find the coefficient of the squared expression.

Answer 4

For example, in 3x^2 + 2y + 7xy + 5, the coefficient of the first term is 3. The coefficient of the second term is 2, and the coefficient of the third term is 7. If a term consists of only variables, its coefficient is 1. Constants are the terms in the algebraic expression that contain only numbers.

Answer 5

y=a(x−h)2+v

Answer 6

?

Answer 7

We know the graph is upside down so we know graph is negative. The answer is either A or B. Now you have to look for the answer.

Answer 8

alright thank you

Answer 9

Your welcome.
