You could do system of equations
g(-1) = 5
1 - b - c = 5
g(2) = 4
16 + 4b - c = 4

but then what

#

also the second equation would be
4 + 2b - c = 4 wouldn't it

also g(-1) = -5

frosty wolf but then what

Solve the system to get c

c = 6 - b
&
c = 2b
?

2² + 2b - c = 4 -> c = 2b
(-1)² + (-1)b - c = -5 -> b + c = 6
b + 2b = 6
3b = 6
b = 2
c = 2(2) = 4
