Question

 a. What is the domain of f? Express your answer in interval notation.

f(x)= 1 - x^4 / x^2 - 1

 b. Use a sequence of values of x near a=1 to estimate the value of limx→1 f(x). The sequence should include values such as 1.01, 1.001, etc. 

c.  Use algebra to simplify the expression 1 - x^4 / x^2 - 1

 d.  True or false: f(1)=-2

e. Based on all of your work above, construct an accurate, labeled graph of y=f(x) on the interval [0,2].
