I would like to know why the following is incorrect:)
** The Polynomial function f(x)=ax^3-bx^2+cx for a,b,and c0, has no y-intercept, exactly three real zeros, and at least one complex zero?

I would like to know why the following is incorrect:)
** The Polynomial function f(x)=ax^3-bx^2+cx for a,b,and c>0, has no y-intercept, exactly three real zeros, and at least one complex zero?

anonymous · Answer

well, first off, the y intercept is the value of y at x=0, and at x=0, y=0, so immediately, saying that it has no y intercept is wrong

anonymous · Answer

the y intercept is what i had, but couldn't find another reason and why.. Thank you :D
