Complete the statements about the key features of the graph of f(x) = x5 – 9x3. As x goes to negative infinity, f(x) goes to neg
Mars2501 [29]
The function is f(x)= x^{5} -9x ^{3}

1. let's factorize the expression x^{5} -9x ^{3}:

f(x)= x^{5} -9x ^{3}= x^{3} ( x^{2} -9)=x^{3}(x-3)(x+3)

the zeros of f(x) are the values of x which make f(x) = 0.

from the factorized form of the function, we see that the roots are:

-3, multiplicity 1
3, multiplicity 1
0, multiplicity 3

(the multiplicity of the roots is the power of each factor of f(x) )


2.  
The end behavior of f(x), whose term of largest degree is x^{5}, is the same as the end behavior of  x^{3}, which has a well known graph. Check the picture attached. 

(similarly the end behavior of an even degree polynomial, could be compared to the end behavior of x^{2})

so, like the graph of x^{3}, the graph of f(x)= x^{5} -9x ^{3} :

"As x goes to negative infinity, f(x) goes to negative infinity, and as x goes to positive infinity, f(x) goes to positive infinity. "

How to find the midpoint of a line segment with 2 given point?
lorasvet [3.4K]
If the 2 given points are endpoints, then we're in business.  The formula for the midpoint is M=( \frac{ x_{1}+ x_{2}  }{2}, \frac{ y_{1} + y_{2} }{2}).  If the endpoints of our segment are the coordinates (1,2) and (12,14), our formula would be filled in as follows: M=( \frac{1+12}{2}, \frac{2+14}{2}) which simplifies to (13/2, 8).  See?  It's pretty simple once you know how to do it.
