Answer:
11+12+13+14=50
Step-by-step explanation:
Just estimate. We know that 15 times 4 = 60, so it has to be less than that. We know that 10 times 4 is 40, so it has to be in that range. Just do trial and error to find the exact answer. I'm editing this now and I realized that I didn't answer the question. I don't know how to write the equation using N but the first integer is 11.
F(x) = -4x - 5
Subtitute the value of x to the equation:
f(-1) = -4 · (-1) - 5 = 4 - 5 = -1
