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. Answer by solver91311(24713) (Show Source):
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: , hence there are no real zeros and therefore no -intercepts.
