Question

The graph of an equation with a negative discriminant always has which characteristic?
A. no x-intercept
B. no y-intercept
C. no maximum
D. no minimum

Answer 1

negative discriminant means imaginary roots so the graph will never cut x axis. hence no x intercepts, so the answer becomes A

Answer 2

@PoetryPrincess
i hope i made u understand

Answer 3

Ah, thank you very much for explaining! =)

Answer 4

see the concavity of graph will depend on the coefficient of x^2 but discriminant suggests real or imaginary or equal roots.
