Question 325692: Using the function f(x)=-(x-1)(x+1)(X-4)(x+4), amswer the questions... What are the x-intercepts? This function is in factored form, multiply it out. What is the y-intercept? What is the end behavior? Fill in the points (2,__)(-2,__) What is the domain of this function? What is the range of this function?

You can put this solution on YOUR website! Using the function f(x)=-(x-1)(x+1)(X-4)(x+4), amswer the questions...
What are the x-intercepts?:::x = 1,-1,4,-4
This function is in factored form, multiply it out.
=-(x^2-1)(x^2-4)
= -x^4-5x^2+4
----------------------
What is the y-intercept?:::-4
--------------------------------
What is the end behavior?:::-inf
--------------------------------
Fill in the points (2,36)(-2,36)
--------------------------------
What is the domain of this function? All Real Numbers
---------------------------------
What is the range of this function? All Real Numbers <=4
=====================================
