Find the x- and y-intercepts of the parabola associated with the quadratic equation. If the parabola does not have any
x-intercepts, state ʺno x-intercepts.ʺ
-$$y = - x ^ { 2 } + 17 x - 72$$
A) No x-intercepts, $( 0,8 )$
B) $( 8,0 ) , ( 9,0 ) , ( 0 , - 72 )$
C) $( 8,0 ) , ( 9,0 ) , ( 0,8 )$
D) $( - 8,0 ) , ( - 9,0 ) , ( 0 , - 72 )$

The x-intercepts are found by setting $ y = 0 $ and solving the quadratic equation $ -x^2 + 17x - 72 = 0 $, which gives the solutions $ x = 8 $ and $ x = 9 $. The y-intercept is found by setting $ x = 0 $, giving $ y = -72 $.
