Answer 1

Respuesta:

Explicación paso a paso:

f(x) = ax² + bx + c

Cuando:

f(-1) = a(-1)² -b + c

f(-1) = a - b + c = -12

f(2) = a(2)² + 2b + c

f(2) = 4a + 2b + c = 6

f(1) = a(1)² + b + c

f(1) = a + b + c = 0

a + c = -b

a - b + c = -12

-2b = -12

b = 6

a + c = -18

4a + c = -6

3a = 12

a = 4

c = -22
