If: y = 2 -2x -x^2 and y = 3x^2 +10x +11

Then: 3x^2 +10X +11 = 2 -2x -x^2

Or: 4x^2 +12x +9 = 0

Factorizing the above: (2x+3)(2x+3) = 0 meaning x = -3/2

When x = -3/2 then by substitution y = 11/4

Therefore point of contact is at: (-3/2, 11/4)

Why is it that the parabolas of y equals x squared -4x plus 8 and y equals 8x -14 - x squared can never intersect with each other giving reasons why not?

Because when collated together the discriminant of b2-4ac = -32 i.e. 144-(4*2*22) = -32 In order for the parabolas to make contact with each other the discriminant must equal zero or be above zero.
