Answer 2

The x intercepts help you to find the 2 solutions.
(x+1) (x-5)
x² -4x -5 = 0
So x =-1 and x=5
The minimum value is found when the derivative is equal to zero.
2x -4=0

So the minimum is at x=2 and
y= 2² -4*2 -5
y=-9

Answer 3

It seems you just need the equation and you'll just need the first 3 lines of my answer.

Answer 4

I was just about to verify that! Thanks for your help.
