I need some help, please. : )

A

Step-by-step explanation:

The y intercept = (0,0) since the c value = 0.

Since the numerical coefficient of x^2 is > 0, the graph opens upward.

a = 1

b = 7

c = 0

The Table describing all the conditions is A

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

angle addition postulate

2x=56
