Q1. a) f(x)= x^2 -4x +k where 1<k<3. What are the coordinates of points where the curve cuts the y-axis and the coordinates of the turning point?

b) The equation f(x)= -2 has two distinct solutions. Find range of values for k


Q2. f(x) = 2x^2 -5x +k for k>4
What are coordinates of points where graph cuts axes and coordinate of turning point

Q1 a

What do you know about the x-coordinate when the curve cuts the y-axis?
So, plug that one into your f and you get your y-axis cut.
Coordinates of the turning point, look in your notes about it. You need to complete the square on it, then read off the info directly.

k is just some constant between 1 and 3, so treat it as a constant. Shouldn't be too confusing here.
