## question

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?

thanks

the bit i was looking for an explanation for was- "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 "

did you answer that bit in the first part of your answer?
