i'm not actually sure what this question is asking me but i've answered the main part of it. it goes:
a straight line has equation where k is a constant, and a parabola has equation . show that the x coordinate of any points of intersection of the line and the parabola satisfy hence find the range of values of k for which the line and parabola do not intersect.
i got the second bit and came up with which i'm sure is right, but i don't understand what its asking me before it says "hence find the range of values etc"
can someone tell me please?
