If you marked option A, then that is not correct. @KathyMae95

OpenStudy (anonymous):

d?

Directrix (directrix):

y = x^2 - 10x + 25 y = (x - 5 )^2 The x squared term is positive so the graph opens upward. (x-5) = 0 when x = 5. So, which option opens upward and "sits" on the x-axis at positive 5? @KathyMae95

Directrix (directrix):

D is wrong - it opens downward.

OpenStudy (anonymous):

so b is is the answer

OpenStudy (anonymous):

no it c

Directrix (directrix):

B opens downward so that is not correct.

OpenStudy (anonymous):

Directrix (directrix):

Okay. Yes, I agree that C is correct.

OpenStudy (anonymous):
