Question 319378: Please help me understand this parabola question. Find the x- and y- intercepts of the graph. y=-3x^2+6x-5, I can't seem to come up with the right numbers to answer this, and not sure how to graph it out afterwards. I came up with (-1,3) but it doesn't look right.

The 
-intercept is trivial. Just substitute 0 for 
and the value of is equal to the constant term, namely -5. Hence, the -intercept is )
The -intercepts are at the real zeros of the polynomial function. Check the discriminant: (-5)\ =\ -24\ <\ 0)
, hence there are no real zeros and therefore no -intercepts.
