na função f (a)= m x+n sabendo que o gráfico passa pelos pontos a(2-3) e b(4,2) DETERMINE:
(a)m+n= (c)m.n
(b)m-n (d)m elevado a N =

A (2; -3)
2m - n = 3
B (4;2)
4m + n = 2
4m - n = 3
2m + n = 2
-----------------
6m = 5
m = 5/6
2.(5/6) + n = 2
10/6 + n = 2
n = 2 - 10/6
n = (2.6-10)/6
n = 2/6
n = 1/3
a) m+n = 5/6 + 1/3 = 5/6 + 2/6 = 7/6
b) m-n = 5/6 - 2/6 = 4/6
c) m.n = 5/6 . 1/3 = 5/18
d) m^n = (5/6)^1/3 = ∛(5/6)
2m - n = 3
