The roots of the resulting polynomial equation are $(x_{1},y_{1}) = (-2,-26)$ , $(x_{2}, y_{2}) = (0.11,1.94)$ and $(x_{3},y_{3}) = (4.39,-9.81)$ , respectively.

Ariana must graph two polynomic expressions: $f(x) = x^{3}-5\cdot x^{2}+2$ and $g(x) = -x^{3}+17\cdot x$ . The roots of the resulting polynomial equation are found by means of this formula:

f(x) - g(x) = 0 (1)

Then, we must look for every point so that f(x) = g(x) .

The roots of the resulting polynomial equation are $(x_{1},y_{1}) = (-2,-26)$ , $(x_{2}, y_{2}) = (0.114,1.937)$ and $(x_{3},y_{3}) = (4.386,-9.812)$ , respectively.

Using a graphing program (see attached picture), the roots are -2, .11, and 4.39.

Note: it took some time to figure out a window that would show both graphs well enough to see the three intersections.

The mean of 2 4 6 8 is 6

bc Means is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.

Step-by-step explanation:

Hope this helps :)
