A) $( - 8,0 ) , ( 1,0 )$
B) $( - 3,0 ) , ( 7,0 )$
C) $( - 1,0 ) , ( - 6,0 )$
D) $( - 8,0 ) , ( - 6,0 )$
E) no $x$-intercept(s)

Quizplus · Accepted Answer

The discriminant of the quadratic equation $x^2 + 6x + 10 = 0$ is $b^2 - 4ac = 6^2 - 4(1)(10) = 36 - 40 = -4$, which is less than 0. This means the equation has no real roots, and thus the graph of the function does not intersect the $x$-axis.
