I'm really stuck on a few questions I have to do. :/
Help would be greatly appreciated.
1. Sketch the graph of: y = (x-2)2 (2x+5) showing all points of interest. The secondary stationary point occurs when x=-1
2. The Parabola y = 2x2 + 5x + 8 and the line y = ax - 10 intersect exactly at one point. Determine value(s) of a and the point of intersection.
3. A truncas has intercepts of (2,0), (6,0), and (0,6). Determine its equation, domain, and range.
4. The remainder when f(x) = 4x4 - 4x3 + jx2 + x + 6 is divided by x-2 is -60. Demonstrate that j must be equal to -25.
Use long division to then factorise f(x)
