g(2)= 2q + r
-7 = 2q + r........(1)
g(-5) = -5q + r
7 = -5q + r..........(2)
2q+r = -7
-5q+r = 7
--------------- —
7q = -14
q = -2
r = -3
g(x) = -2x - 3
g(4) = -8 -3 = -11
g(2)= -7
g(-5) = 7.
D2 : g(4) = ?
D3 : g(2) = 2q+r = -7
g(-5) = -5q+r = 7
--------------------- -
7q = -14
q = -14/7
q = -2
2q + r = -7
2(-2) + r = -7
-4 + r = -7
r = -7+4
r = -3
Maka g(4) = 4(-2) + (-3)
= -8-3
= -11
