Answer:
To add or subtract functions, just add or subtract the values at each point where it makes sense. If the functions are given by formulas, you can just add or subtract the formulas (it doesn't matter whether you plug in values before or after).
Step-by-step explanation:
What a questions equals out to be.
Answer:
k'=3,-6
l'=3,1
m'=8,1
n'=8,-6
Step-by-step explanation:
A) n^2 -16n+69 = (n-8)^2 - 64 + 69 = (n-8)^2+5
B) vertex (n,g(n)) = (8, 5). It's a minimum because for any other value of n, (n-8)^2 is positive and it adds (positive sign before the ()^2)
C) n=8 is the axis of symmetry (it is the horizontal value of the vertex)
