For (h+g)(x) you just add the two functions:
(h+g)(x) = 4x + 2x^2
For (h•g)(x) you multiply them:
(h•g)(x) = 4x • 2x^2 = 8x^3
For (h-g)(x) you subtract them:
(h-g)(x) = 4x - 2x^2
For (h-g)(-2) you sub -2 into the equation we just created:
(h-g)(-2) = 4(-2) - 2(-2)^2
(h-g)(-2) = -8 - 2(4)
(h-g)(-2) = -8 - 8
(h-g)(-2) = -16

Step-by-step explanation:
Answer:
The diagonals of a square intersect cross in a 90 degree angle. This means that the diagonals of a square are perpendicular. The diagonals of a square are the same length congruent.
Step-by-step explanation:
so the answer is perpendicular
