The answer is n = -4. To get that, is to multiply the whole thing by 2 and then solve.
2×(n/2) + 5=3
(Canceled out the 2) n +10 = 6
N = -4 (by subtracting 10)
At f(-3) the graph is equal to -9.
In order to find the point on the graph, move over to -3 on the x axis. Then move down to find the point where it hits the parabola. You'll see that the parabola hits at point (-3, -9).
Answer:
-8x-4 is the answer using distributive property.
