Answer 1

Explicación paso a paso:

1.f(-3) = (-3)^{2} - 2(-3) -3f(−3)=(−3)

2

−2(−3)−3 => f(-3) = 12

f(-2) = (-2)^{2} - 2(-2) -3 => f(-2) = 5f(−2)=(−2)

2

−2(−2)−3=>f(−2)=5

f(-1) = (-1)^{2} -2(-1) - 3 => f(-1) = 0f(−1)=(−1)

2

−2(−1)−3=>f(−1)=0

f(0) = (0)^{2} -2(0) - 3 => f(0) = -3f(0)=(0)

2

−2(0)−3=>f(0)=−3

f(1) = (1)^{2} -2(1) - 3 => f(1) = -4f(1)=(1)

2

−2(1)−3=>f(1)=−4

f(2) = (2)^{2} -2(2) - 3 => f(2) = -3f(2)=(2)

2

−2(2)−3=>f(2)=−3

f(3) = (3)^{2} -2(3) - 3 => f(3) = 0f(3)=(3)

2

−2(3)−3=>f(3)=0

2.f(x) = – x2 + 5x – 6

0 = -4+5x

-5x=-4

x=4/5

espero que te ayude ^_^
