Answer:
I really hope it's correct that was the first time I did smth like this one
We must graph y=x^3-9x^2+11x+21. Please, see the attached file.
Then we see were the graph cuts the x-axis, and these values of x are the real solutions of the given equation:
The real solutions of the given equation are:x = -1, 3, and 7
B lmk if I’m right have a gud day
Well, the negative rotates it around x. Then the 1/2 stretches it.
Csc(x) has a period of 2pi. So now it has a period of 4pi. If you want a
